[U-Boot] AHCI driver is quiet slow
by Yaroslav K. 15 Jul '16

15 Jul '16

Hello! I'm using U-boot with x86 hardware (Atom C2000) and Linux, and I've noticed that the AHCI driver in U-boot is quiet much slower than the one in Linux. The drive connected is an 8 GB SATA SSD. U-boot: => time scsi read 0x10000000 0 0x100000 SCSI read: device 0 block # 0, count 1048576 ... 1048576 blocks read: OK time: 2 minutes, 19.318 seconds Linux: # sync && echo 3 > /proc/sys/vm/drop_caches # time dd if=/dev/sda of=/dev/null count=1048576 1048576+0 records in 1048576+0 records out real 0m 26.75s user 0m 0.40s sys 0m 2.72s Is there maybe anything that could be done to improve AHCI performance? -- Yaroslav

[U-Boot] [PATCH v2 0/5] add support for rk3399 soc and evb
by Kever Yang 15 Jul '16

15 Jul '16

This patchset add support for rk3399 with ATF based on Rockchip miniloader as secondary bootloader instead of u-boot SPL. Rockchip miniloader init the DRAM and load the ATF and u-boot to runing address, and then jump to ATF, ATM do some init and switch to EL2/EL1 mode before jump to next loader which is u-boot here. Pls reference board/rockchip/evb_rk3399/README to setup the board. Will migrate to SPL once its ready for ATF. This patch set is based on below patch: "board: move all the rockchip board in one folder" This patch set has been test on rk3399 evb board.

[U-Boot] [RFC PATCH 0/7] "Transient" (= export-restricted) environment vars
by Bernhard Nortmann 15 Jul '16

15 Jul '16

This series evolved around the idea of introducing a new env_op type to control (and possibly restrict) the export of variables. This is especially useful if one wants to prevent dynamic configuration information from ending up in a saved environment - the 'classic' example being network setup with "dhcp" followed by the "saveenv" command. (The networking case is even further complicated by the fact that users may actually wish to setup and save a static IP configuration manually, which means that "locking up" the corresponding variables right away isn't a viable solution.) See also: http://lists.denx.de/pipermail/u-boot/2015-September/227611.html http://lists.denx.de/pipermail/u-boot/2016-April/250237.html Regards, B.

[U-Boot] [PATCH v3 00/62] dm: rockchip: sandbox: Add support for compiled-in platform data
by Simon Glass 15 Jul '16

15 Jul '16

Note: This v3 series adds a test and fixes a few bugs found in generation of of-platdata. This series provides a way to compile in the contents of a device tree as C code into U-Boot, implementing an idea that Tom Rini came up with. It is intended to deal with extremely tight environments where there is not enough space for the ~3KB device tree code overhead. Examples include SPL where there is only 16KB of available RAM yet a full MMC stack is required. To provide a reasonable test environment, SPL support is added to sandbox, through a new 'sandbox_spl' target. A new tool 'dtoc' converts device tree data to C code (and structure definitions). To check its effectiveness for a real application, the v2 series includes support for enabling of-platdata for a rockchip board (firefly-rk3288). The results are as follows: Code Data u-boot-spl.bin size of-platdata disabled 23159 1624 28864 of-platdata enabled 19093 2616 21761 Overall the saving is 7103 bytes, about 7KB. Approximately 4KB of this comes from removing the device tree data from SPL although this is offset by the size of the of-platdata itself (around 1KB). On top of this effective 3KB reduction, another ~3KB reduction comes from dropping libfdt and a further 1KB from dropping unused setup and driver-model code. Clearly this approach does have value. Looked at with a favourable light it provides the best of both worlds: configuration using standard device tree bindings without the run-time overhead. Looking under the hood shows a less rosy picture. Effectively we end up with a new set of C structures which must be handled by the driver. This series suggests a suitable approach for dealing with this (see of-plat.txt) which is workable. However there are a number of serious caveats. See that file for details. Thsi feature should be used sparingly. Rockchip is to some extent an unusual case: lots of features (leading to a large SPL device tree size of 4KB), no MMC stack available to SPL from the internal ROM* and a very limited maximum SPL code size. Most SoCs will not benefit from this. However, for an SoC with very small SRAM where only a few drivers are needed in SPL (such as serial and MMC) then of-platdata could provide a useful benefit, without a significant increase in complexity. With the v3 series this feature is ready for use. It is available at u-boot-dm/dt-working. The dtoc tool might be better renamed fdttoc (which is clumsy) or fdt2c. Ideas welcome. Summary of changes in this series: - New sandbox_spl board - Generation of C code from device tree (dtoc tool) - Conversion of some core driver-model uclasses to support of-platdata - Conversion of firefly-rk3288 to use of-platdata - Some minor additions to the test/py framework * Note that the rockchip internal ROM does include an MMC stack but it only permits loading of data in its own format, outside control of U-Boot. Changes in v3: - Rebase to master - Print out the of-platdata contents for testing - Update to the new clock API - Update comments a little - Add GetEmpty() to obtain an empty/zero value of a given type - Process the structs in a first pass, to correct bugs in widening - Fix handling of boolean value (no impact, but it is more correct) - Enhance widening to handle array size changes - Don't try to expand when there is no of-platdata - Add new patch to avoid bringing in the eeprom emulator in SPL - Rebase to master - Rebase to master - Add new patch to handle testing with the sandbox_spl board - Add new patch to note which console produced unexpected output - Add new patch to provide a way to get early console output - Add new patch to start sandbox SPL when enabled - Add new patch to test of-platdata - Add a test for of-platdata Changes in v2: - Add a comment to the effect that 64-bit machines are not supported -

[U-Boot] [PATCH v3 0/4] rockchip: rk3288: add fastboot support
by Ziyuan Xu 15 Jul '16

15 Jul '16

This patchset add the fastboot support for rk3288, and I have tested on firefly-rk3288 board. Fix an issue which was mentioned in V1's cover-letter: The DMA buffer was always zero after DMA transfer is complete, It takes no effect that invalidate dcache after the DMA is complete and before the CPU reads it. It's important to invalidate dcache before starting DMA, ensure coherency and prevent from any dirty lines in the cache which from the DMA buffer. Summary of changes in this series: - Achieve UOC_CON_OFFSET physical address from DT - Make UOC_CON registers to be unfixed which should be got from DT - Add new commit dd77b11fd44a84 (usb: dwc2: Invalidate dcache before staring DMA) Changes in v3: - Make UOC_CON registers to be unfixed which should be got from DT - Achieve UOC_CON_OFFSET physical address from DT - New commit since v3 to fix the coherence issue between memory and cache Changes in v2: - Rename rk3288_usb_phy.c to rockchip_usb_syno_phy.c - Rework the behaviour in otg_phy_init() and otg_phy_off() - Update detailed commit message - Modify the macro's values - Achieve the regs_phy from DT - Update comments a little Xu Ziyuan (4): usb: rockchip-phy: implement USB2.0 phy control for Synopsys usb: dwc2-otg: re-define fifo-size for Rockchip SoCs rockchip: rk3288: add fastboot support usb: dwc2: invalidate dcache before starting DMA arch/arm/dts/rk3288.dtsi | 1 + arch/arm/mach-rockchip/board.c | 60 ++++++++++++++++++++++++++++++ drivers/usb/gadget/dwc2_udc_otg_regs.h | 6 +++ drivers/usb/gadget/dwc2_udc_otg_xfer_dma.c | 3 ++ drivers/usb/phy/Makefile | 1 + drivers/usb/phy/rockchip_usb_syno_phy.c | 47 +++++++++++++++++++++++ include/configs/rk3288_common.h | 26 +++++++++++++ 7 files changed, 144 insertions(+) create mode 100644 drivers/usb/phy/rockchip_usb_syno_phy.c -- 1.9.1

In preparation for RK3368 and RK3399, which need to select ARM64, don't select CPU_V7 at the ARCH_ROCKCHIP level but at the SoC level instead.
