[U-Boot] dm: device_id info
by Jagan Teki 13 Jan '15

13 Jan '15

Hi, I'm exploring internals of dm where I'm just comparing udevice with Linux model especially on device_id scenarios. udevice_id - u-boot Linux: -------- platform_device_id of_device_id spi_device_id input_device_id .............. ....... pci_device_id 1. Does this udevice_id is a generic model in u-boot for all variant of devices? Bcz Linux defines each devices have own device_id entries. 2. diff of of_device_id vs udevice_id 3. udevice_id vs fdt function calls, suppose If I write a dm driver where my board doesn't have fdt support, is this a valid scenario. 4. Pls- add any info which I haven't covered. thanks! -- Jagan.

[U-Boot] [Question] DM SPI FLASH
by Peng Fan 13 Jan '15

13 Jan '15

Hi Simon, I am hacking DTB and DM SPI FLASH support for i.MX 6SoloX. I have a question about `sf probe`. In original way, `sf probe` or `sf probe 0:0` can detect qspi flashes on my platform. But after using DM, I should use `sf probe 35536896:0` to probe flashes. 35536896 is the address of QSPI controller's reg base 0x021e4000 in hex format. Does I miss something in my driver? It seems dev->seq is not valid so should pass req_seq which is the address of qspi controller in dts file. Any ideas? The log using `sf probe 0:0`. Fail to probe flash => sf probe 0:0 uclass_find_device_by_seq: 0 0 - 35536896 35536896 - not found spi_find_bus_and_cs: No bus 0 uclass_find_device_by_seq: 0 0 - 35536896 35536896 - not found uclass_find_device_by_seq: 1 0 - 35536896 35536896 - not found Invalid bus 0 (err=-19) Failed to initialize SPI flash at 0:0 (error -19) The log using `sf probe 35536896:0`.

[U-Boot] [PATCH v2 0/11] Add support for caching Memory Reference Code data
by Simon Glass 13 Jan '15

13 Jan '15

Since the memory reference code is so slow on x86, add a feature to bypass this, storing the previous parameters in SPI flash. This saves around 500ms on each boot. Also enable a SPI flash environment. Changes in v2: - Use intel,ich-spi as the compatible string - Refactor IP checksum patches - Refactor IP checksum patches - Adjust the mc146818 driver instead of adding a new cmos.h header - Make changes to chromebook_link.dts since link.dts is gone - Use intel,ich-spi as the compatible string - Update for the new CMOS RAM access functions in the RTC - Add a comment about why both CMOS RAM and SPI flash are used for the cache Simon Glass (11): x86: dts: Add compatible string for Intel ICH9 SPI controller x86: Move ipchecksum into common area and rename it x86: Allow adding of IP checksums x86: rtc: mc146818: Add helpers to read/write CMOS RAM x86: spi: Add device tree support Allow architecture-specific memory reservation x86: dts: Add SPI flash MRC details for chromebook_link x86: Implement a cache for Memory Reference Code parameters x86: config: Enable hook for saving MRC configuration x86: ivybridge: Drop the Kconfig MRC cache information x86: config: chromebook_link: Enable environment arch/x86/cpu/Makefile | 1 + arch/x86/cpu/coreboot/Makefile | 1 - arch/x86/cpu/coreboot/ipchecksum.c | 55 ------ arch/x86/cpu/coreboot/tables.c | 8 +- arch/x86/cpu/ip_checksum.c | 55 ++++++ arch/x86/cpu/ivybridge/Kconfig | 28 --- arch/x86/cpu/ivybridge/Makefile | 1 + arch/x86/cpu/ivybridge/mrccache.c | 156 +++++++++++++++ arch/x86/cpu/ivybridge/sdram.c | 253 ++++++++++++++++++++++++ arch/x86/dts/chromebook_link.dts | 15 +- arch/x86/dts/link.dts | 229 +++++++++++++++++++++ arch/x86/include/asm/arch-coreboot/ipchecksum.h | 37 ---- arch/x86/include/asm/arch-ivybridge/mrccache.h | 51 +++++ arch/x86/include/asm/global_data.h | 3 + arch/x86/include/asm/ip_checksum.h | 16 ++ common/board_f.c | 7 + drivers/rtc/mc146818.c | 53 +++-- drivers/spi/ich.c | 7 + include/configs/chromebook_link.h | 8 + include/configs/x86-common.h | 1 + include/fdtdec.h | 1 + include/rtc.h | 32 +++ lib/fdtdec.c | 1 + 23 files changed, 879 insertions(+), 140 deletions(-) delete mode 100644 arch/x86/cpu/coreboot/ipchecksum.c create mode 100644 arch/x86/cpu/ip_checksum.c create mode 100644 arch/x86/cpu/ivybridge/mrccache.c create mode 100644 arch/x86/dts/link.dts delete mode 100644 arch/x86/include/asm/arch-coreboot/ipchecksum.h create mode 100644 arch/x86/include/asm/arch-ivybridge/mrccache.h create mode 100644 arch/x86/include/asm/ip_checksum.h -- 2.2.0.rc0.207.ga3a616c

[U-Boot] [ANN] U-Boot v2015.01 released
by Tom Rini 12 Jan '15

12 Jan '15

Hey all, I've pushed v2015.01 out to the repository and tarballs should exist soon. As v2014.10 was our first release with Kconfig, v2015.01 is when we've started migrating things from include/configs/* and into Kconfig files for real. We've got a way to go but I want to thank people for pushing this along. Second, as much as I don't like to single out a single SoC here, I do want to thank the folks doing Allwinner work as with this release the community has switched to mainline for the linux-sunxi project[1]. In device model work, we now have support for SPI and I2C upstream (and other stuff will be going in with the merge window opening). In not entirely unrelated news, our x86 support now has bare ROM functionality for ivybridge and one Atom platform. Two last things, in addition to the general part about improved platform / feature support all over the place, likely including your favorite board. First, as I said last release, we're strongly considering deprecating "MAKEALL" in favor of the buildman tool we've also had for the last almost two years. So please, try it out and report back problems you see that would prevent you from switching over or a use case you have that can't seem to be found there. Second, as per some discussions on the mailing list for a while (And build warnings), boards that don't support CONFIG_SYS_GENERIC_BOARD are to be removed. This release is that last one that those boards will be in, and anything still not converted by v2015.04-rc1 will be dropped. And I would encourage custodians to follow-up with anything big I've overlooked. Thanks for the hard work everyone! The merge window is now open and will close on Saturday January 31st.
