[U-Boot] [PATCH v3 00/11] mx6: SPL NAND support
This series adds some necessary framework for IMX6 SPL support. The series includes support for NAND SPL and has been tested with MMC as well. I have tested this on five differing Ventana baseboards with a variety of memory (32bit 512MB, 32bit 1024MB, 64bit 1024MB) and CPU configurations (IMX6Q, IMX6DL, IMX6S).
This is based on top of Mashahiro Yamada's patch that consolidates arch/arm/include/asm/arch-*/spl.h [1]
v3: - re-ordered calls in board_init_f - replace imx_iomux_v3_setup_multiple_pads_array with additional intelligence in imx_iomux_v3_setup_multiple_pads - added ifdef's around cpu specific mmdc iocfg functions for code-reduction with single-variant board configs - added checks for IMX6D - added Freescale copyright to boot device support function - fixed typo s/IMX6SLD/IMX6SDL - encorporated cleanups in mxs_nand_spl.c per feedback
v2: - use compatible linker script instead of creating new one - remove structure passing data from SPL to u-boot - remove dependence on mtdpart, mtdcore, nand_util, nand_ecc, nand_base and nand_bbt to bring SPL down in size. This reduced codesize by about 32k where now mxs_spl_nand is about 12k total - adjust CONFIG_SPL_TEXT_BASE, CONFIG_SPL_STACK and CONFIG_SPL_MAX_SIZE to accomodate the IMX6SOLO/DUALLITE which have half the iRAM of the IMX6DUAL/IMX6QUAD - move boot dev detection into imx-common/spl.c - move macros for using pinmux array into iomux-v3.h - remove missing/unnecessary include - revert mtdparts change - use get_ram_size() to detect memory - add support for MX6SOLO and MX6DUAL - set CS0_END for 4GB so get_ram_size() works - updated DDR3 calibration values for ventana boards - fixed build issue - only compile spl if doing spl build - fixed line length issue in README - remove CONFIG_SPL* conditions and conditionally compile instead - removed prints for CPU type and DRAM size/width - uboot will print these l - removed unused gw_ventana_spl.cfg - use common read_eeprom function - added MMC support to SPL - added Masahiro Yamada's boot mode consolidation patch http://patchwork.ozlabs.org/patch/341817 and rebase on top of it

We only need to read in the size of struct image_header and thus don't need to know the page size of the nand device.

When and by whom will this patch be applied?
Since this is not IMX-specific, I'd like this patch to be applied first.
Best Regards Masahiro Yamada

It is not iMX specific, but in the last iteration Scott acked it and give us indication to let it in the patchset - plan was to apply the patchset as a whole in one shot, that is by me.
I can propose I apply this (and maybe a couple of other patches in this patchset that have already passed the review and they were acked) and this is part of my next pull request to Albert. Or maybe Tom decides to apply it directly to master, and Tim drops it from the patchset.
Best regards, Stefano

As discussed : applied to u-boot-imx, thanks.
Tim, please remove it in your next post, thanks.

This utilizes existing mxs_nand support layer to provide a method to load an image off nand for SPL. The flash device will be detected in order to support multiple flash devices instead of having layout hard coded at build time.

Its hard to say - I think the use of BOOT_DEVICE_* is very implementation specific. I don't quite understand why there is a BOOT_DEVICE_MMC{1,2,2_2} defined in arch/arm/include/asm/spl.h - the BOOT_DEVICE_MMC2_2 is certainly quite odd. In uboot/common/spl/spl.c they are all treated the same and spl_mmc_load_image() always assumes the 'first' mmc device anyway.
In the IMX6 case I'm not sure an SD/uSD card would be treated any different than an MMC card so it would come down to which specific device is flagged as the boot device, of which there are 4 sdhc's. So eventually, one might need to add more BOOT_DEVICE_MMC enums if that is to be supported. For now, I'm keeping it simple and there is an issue with IMX6 spl_mmc_load_image() anyway which I plan on addressing later.

AFAIK, this is needed to support eMMC boot partitions which are physical and not logical, but they are still within the same device.
In uboot/common/spl/spl.c they are all treated the same and spl_mmc_load_image() always assumes the 'first' mmc device anyway.

Add memory-mapped structures for MMDC iomux and configuration. Note that the MMDC configuration registers are common between the IMX6DQ (IMX6DUAL/IMX6QUAD) and IMX6SDL (IMX6SOLO/IMX6DUALLITE) the iomux register addresses differ. This requires two sets of structures.
Add structures to describe DDR3 device information, system information (memory layout, etc), and MMDC calibration regitsers that can be used to configure the MMDC dynamically.
We define these structures for SPL builds instead of including mx6q-ddr.h an mx6dl-ddr.h which use the same namespace and are only useful for imximage cf files.

We define these structures for SPL builds instead of including mx6q-ddr.h an mx6dl-ddr.h which use the same namespace and are only useful for imximage cf files.
What about the usefulness of the structs for U-Boot code? For example, it might be necessary for U-Boot code to query the MMDC registers to setup memory related variables like gd->ram_size and gd->bd->bi_dram[i].size. Sure this can be done using the #defines in the header files, but we lose nothing by making the structs available to U-Boot as well.

perhaps, but I would assume if anyone needs these in u-boot they can broaden the scope when needed. There is an imx_ddr_size() function in spl/arch/arm/imx-common/cpu.c that returns dram size based on MMDC configuration already, yet it uses a subset of this structure that is common to imx in general.

Agree. At the moment, there is only one user of the structure and it is ok.

- add function for configuring iomux based on board-specific regs - add function for configuring mmdc based on board-specific and chip-specific data
Signed-off-by: Tim Harvey tharvey@gateworks.com --- v4: - added delay following configure to allow ZQ calibration to complete - update MMDC configuration to match Freescale RM
v3: - added ifdef's around cpu specific iocfg functions for code-reduction with single-variant board configs - moved portions from previous patch here - added check for IMX6D
v2: - split out mmdc and iomux structs into separate patch --- arch/arm/cpu/armv7/mx6/Makefile | 1 + arch/arm/cpu/armv7/mx6/ddr.c | 490 ++++++++++++++++++++++++++++++++ arch/arm/include/asm/arch-mx6/mx6-ddr.h | 72 +++++ 3 files changed, 563 insertions(+) create mode 100644 arch/arm/cpu/armv7/mx6/ddr.c

Allow imx_iomux_v3_setup_multiple_pads to take a multi-cpu pad_list and add macros for declaring the pad_list that take into account the SoC types supported using CONFIG_MX6QDL (supports both the MX6Q and MX6DL iomux).
Signed-off-by: Tim Harvey tharvey@gateworks.com --- v3: - remove commit msg 2nd paragrap about prior approaches - re-work to avoid needing to add a new function by making imx_iomux_v3_setup_multiple_pads more intelligent and adding macros that depend on SoC type support
v2: - moved macros for declaring and using structs for array variant - removed non-related whitespace cleanup --- arch/arm/imx-common/iomux-v3.c | 16 ++++++++++++++-- arch/arm/include/asm/imx-common/iomux-v3.h | 25 +++++++++++++++++++++++++ 2 files changed, 39 insertions(+), 2 deletions(-)

Switch to an SPL image. The SPL for Ventana does the following: - setup i2c and read the factory programmed EEPROM to obtain DRAM config and model for board-specific calibration data - configure DRAM per CPU/size/layout/devices/calibration - load u-boot.img from NAND and jump to it
This allows for a single SPL+u-boot.img to replace the previous multiple boa configurations.
Signed-off-by: Tim Harvey tharvey@gateworks.com --- v3: - re-ordered calls in board_init_f
v2: - remove missing/unnecessary include - revert mtdparts change - use imx_ddr_size() which uses MMDC configuration to determine mem size explicitly - add support for MX6SOLO and MX6DUAL - set CS0_END for 4GB so get_ram_size() works - updated DDR3 calibration values for ventana boards - fixed build issue - only compile spl if doing spl build - fixed line length issue in README - remove CONFIG_SPL* conditions and conditionally compile instead - removed prints for CPU type and DRAM size/width - uboot will print these later - removed unused gw_ventana_spl.cfg - use common read_eeprom function - added MMC support to SPL --- board/gateworks/gw_ventana/Makefile | 1 + board/gateworks/gw_ventana/README | 92 +++--- board/gateworks/gw_ventana/gw_ventana.c | 10 +- board/gateworks/gw_ventana/gw_ventana.cfg | 15 - board/gateworks/gw_ventana/gw_ventana_spl.c | 419 ++++++++++++++++++++++++++++ boards.cfg | 6 +- include/configs/gw_ventana.h | 11 + 7 files changed, 498 insertions(+), 56 deletions(-) create mode 100644 board/gateworks/gw_ventana/gw_ventana_spl.c

Hi Tim,
I cannot build with this version. A setup for a couple of pins is not yet replaces.
In fact, I have:
/* Enable Backlight */ imx_iomux_v3_setup_pad(MX6_PAD_SD1_CMD__GPIO1_IO18 |
and it should be:
SETUP_IOMUX_PAD(PAD_SD1_CMD__GPIO1_IO18 |
The same some lines later:
/* Backlight CABEN on LVDS connector */ - imx_iomux_v3_setup_pad(MX6_PAD_SD2_CLK__GPIO1_IO10 | + SETUP_IOMUX_PAD(PAD_SD2_CLK__GPIO1_IO10 |
Can you check and fix it ? Thanks !
Regarding your patchset: I had no remarkable comments and, as I have not seen any comments from other developers, your patchset is ready to be merged. I am also waiting for Masahiro's patch to be applied.
Best regards, Stefano Babic

Stefano,
Those should be patched from patch 10. However, I can't seem to get patch 9 to apply cleanly from current u-boot-imx/master so perhaps I should just rebase the whole series and post again?

Stefano,
Those should be patched from patch 10.
Sure ? Patch 10 replaces a lot of occurrencies, but I do not see the ones introduced by "imx: ventana: add HDMI and LVDS display capability" that is already applied.
However, I can't seem to get patch 9 to apply cleanly from current u-boot-imx/master so perhaps I should just rebase the whole series and post again?
Please take a look and repost if required. If you repost, you could also fix yourself this styling issue in Patch 3:
ERROR: return is not a function, parentheses are not required #192: FILE: drivers/mtd/nand/mxs_nand_spl.c:138: + return (chip->oob_poi[0] != 0xff);

This series adds some necessary framework for IMX6 SPL support. The series includes support for NAND SPL and has been tested with MMC as well. I have tested this on five differing Ventana baseboards with a variety of memory (32bit 512MB, 32bit 1024MB, 64bit 1024MB) and CPU configurations (IMX6Q, IMX6DL, IMX6S).
This is based on top of Mashahiro Yamada's patch that consolidates arch/arm/include/asm/arch-*/spl.h [1]
v3:
- re-ordered calls in board_init_f
- replace imx_iomux_v3_setup_multiple_pads_array with additional intelligence in imx_iomux_v3_setup_multiple_pads
- added ifdef's around cpu specific mmdc iocfg functions for code-reduction with single-variant board configs
- added checks for IMX6D
- added Freescale copyright to boot device support function
- fixed typo s/IMX6SLD/IMX6SDL
- encorporated cleanups in mxs_nand_spl.c per feedback
v2:
- use compatible linker script instead of creating new one
- remove structure passing data from SPL to u-boot
- remove dependence on mtdpart, mtdcore, nand_util, nand_ecc, nand_base and nand_bbt to bring SPL down in size. This reduced codesize by about 32k where now mxs_spl_nand is about 12k total
- adjust CONFIG_SPL_TEXT_BASE, CONFIG_SPL_STACK and CONFIG_SPL_MAX_SIZE to accomodate the IMX6SOLO/DUALLITE which have half the iRAM of the IMX6DUAL/IMX6QUAD
- move boot dev detection into imx-common/spl.c
- move macros for using pinmux array into iomux-v3.h
- remove missing/unnecessary include
- revert mtdparts change
- use get_ram_size() to detect memory
- add support for MX6SOLO and MX6DUAL
- set CS0_END for 4GB so get_ram_size() works
- updated DDR3 calibration values for ventana boards
- fixed build issue - only compile spl if doing spl build
- fixed line length issue in README
- remove CONFIG_SPL* conditions and conditionally compile instead
- removed prints for CPU type and DRAM size/width - uboot will print these l
- removed unused gw_ventana_spl.cfg
- use common read_eeprom function
- added MMC support to SPL
- added Masahiro Yamada's boot mode consolidation patch http://patchwork.ozlabs.org/patch/341817 and rebase on top of it

Stefano,
Any comments on this series? I realize you've applied the first one and I'll remove that from any subsequent posts.
Regards,
Tim

Right.
I think we have a very good point (nice work !) and we are near to merge the patchset. If I am not wrong, you want to post an update for the MMDC config patch, do you ?
Patch 2 should be acked by Scott because it belongs to his area of competence.
Best regards, Stefano Babic

Yes, I do have an update for that particular patch, but I don't think anyone has commented on that patch either way. I'll go ahead and respond to that thread with my update as that is the only non-submitted change I have.
Thanks,
Tim
