[U-Boot] [v2, 1/5] mmc: fsl_esdhc: don't set XFERTYP_RSPTYP_48_BUSY for CMD with busy response
by Yangbo Lu 14 Nov '16

14 Nov '16

For CMD with busy response, the eSDHC driver would poll DAT0 until CMD completion rather than polling IRQSTAT. So, don't set XFERTYP_RSPTYP_48_BUSY to avoid interrupts (DTOE or TC) in IRQSTAT.

[U-Boot] [PATCH v2 0/5] Raspberry Pi EFI enablement
by Alexander Graf 14 Nov '16

14 Nov '16

This is a follow-up to the RTS patch set from yesterday. With this patch set I can successfully boot a Raspberry Pi 3 into Linux, with efifb, efi based reset/power off and spin table secondary bringup working. I've put all of this into a single patch set so it doesn't get lost. In theory most patches could live by themselves, but it doesn't make much sense to introduce frameworks without adding users to them :). Enjoy, Alex Alexander Graf (5): efi_loader: Allow boards to implement get_time and reset_system ARM: bcm283x: Implement EFI RTS reset_system efi_loader: gop: Expose fb when 32bpp bcm2835 video: Map frame buffer as 32bpp bcm2835: Reserve the spin table in efi memory map arch/arm/mach-bcm283x/include/mach/wdog.h | 2 +- arch/arm/mach-bcm283x/reset.c | 59 +++++++++++++++-- board/raspberrypi/rpi/rpi.c | 6 ++ cmd/bootefi.c | 4 ++ drivers/video/bcm2835.c | 6 +- include/configs/rpi.h | 2 +- include/efi_loader.h | 18 ++++++ lib/efi_loader/efi_gop.c | 16 +++++ lib/efi_loader/efi_runtime.c | 101 ++++++++++++++++++++++++++---- 9 files changed, 192 insertions(+), 22 deletions(-) -- 1.8.5.6

[U-Boot] [PATCH 1/3] igep00x0: disable CONFIG_DISPLAY_BOARDINFO
by Ladislav Michl 13 Nov '16

As a single U-Boot binary can now run on various board modifications, drop CONFIG_DISPLAY_BOARDINFO as there's no known way to distinguish between them. Also saves few bytes as a bonus.

[U-Boot] [PATCH 1/4] ARM: tegra: add SoC-level hook for board_late_init()
by Stephen Warren 07 Nov '16

07 Nov '16

From: Stephen Warren <swarren(a)nvidia.com> Extend the Tegra186 implementation of board_late_init() to call a per-SoC "hook" function. This will allow SoC-specific (rather than Tegra-wide) functionality to be implemented without the core Tegra code needing to be aware of the details. While board186.c is currently only used for Tegra186, it should be applicable to any other future SoC, and perhaps its simple design could be back-ported to older SoCs in the future too. Signed-off-by: Stephen Warren <swarren(a)nvidia.com> --- This series logically relies on the DWC EQOS driver series that I just sent in order for the device to actually work. However, the code should compile and even run (albeit without yet enabling Ethernet) even without both series applied. So, the two series don't need to be applied in any particular order, nor in the same branch. arch/arm/mach-tegra/board186.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-tegra/board186.c b/arch/arm/mach-tegra/board186.c index 1b9799fd80c2..38261e421cc1 100644 --- a/arch/arm/mach-tegra/board186.c +++ b/arch/arm/mach-tegra/board186.c @@ -26,11 +26,16 @@ int board_init(void) return tegra_board_init(); } -int board_late_init(void) +__weak int tegra_soc_board_init_late(void) { return 0; } +int board_late_init(void) +{ + return tegra_soc_board_init_late(); +} + void pad_init_mmc(struct mmc_host *host) { } -- 2.9.3

From: Hongbo Zhang <hongbo.zhang(a)nxp.com> This patch set introduces ARMv8 PSCI framework, all the PSCI functions are implemented a default dummy one, it is up to each platform to implement their own specific ones. The first 1/6 patch is a prepare clean up for adding ARMv8 PSCI. Patches 2/6 to 5/6 introduce new ARMv8 framework and set it up. The last 6/6 adds a most simple implementation on NXP LS1043 platform, to verify this framework. This patch set mainly introduces ARMv8 PSCI framework, for easier review and merge, further PSCI implementation on LS1043 is coming later.

[U-Boot] [PATCH v3 0/7] clk: at91: Improve the clock implementation
by Wenyou Yang 28 Oct '16

28 Oct '16

Add the clock ops for such as spi0_clk, which is the real clock provider, instead of periph32ck, which only recursively bind its children as clk devices. Also update the clocks called in the drivers. Changes in v3: - Remove the unneeded wrapper functions. - Fix typo, Invaild -> Invalid. - Add Acked-by tag. - Fix typo, unneccessary -> unnecessary. - Add Reviewed-by tag. Changes in v2: - Add Acked-by tag. - For the periph32ck, periph64ck, gck, systemck nodes, they aren't the clock providers, are to house various actual clock providers, use UCLASS_MISC, instead of UCLASS_CLK. - For *_of_xlate(), add argument check. - Fix the implementation of the *_get_rate(). - Use documentation-wise variables for *_clk_probe(). - Remove the duplicated code, use the common functions. - Add Acked-by tag for gpio/atmel_pio4.
