2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-25rockchip: rk3188: use DM timer instead of rk_timerKever Yang
Disable rk_timer as SYS timer and use DM timer instead, so that we can get a better timer framework, the rk_timer is going to be clean after we conver to use DM timer or ARM arch/generic timer.

2018-02-07spl: eMMC/SD: Provide one __weak spl_boot_mode() functionLukasz Majewski
The goal of this patch is to clean up the code related to choosing SPL MMC boot mode. The spl_boot_mode() now is called only in spl_mmc_load_image() function, which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled. To achieve the goal, all per mach/arch implementations eligible for unification has been replaced with one __weak implementation.

2017-11-21rockchip: back-to-bootrom: allow passing a cmd to the bootromPhilipp Tomsich
The BROM supports forcing it to enter download-mode, if an appropriate result/cmd-word is returned to it. There already is a series to support this in review, so this prepares the (newly C-version) of the back-to-bootrom code to accept a cmd to passed on to the BROM. All the existing call-sites are adjusted to match the changed function signature. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Andy Yan <andy.yan@rock-chips.com>
2017-11-21rockchip: rk3188: use boot0 hook to load up SPL in 2 stepsPhilipp Tomsich
For the RK3188, the BROM will attempt to load up the first stage image (SPL for the RK3188) in two steps: first 1KB to offset 0x800 in the SRAM and then the remainder to offset 0xc00 in the SRAM. It always enters at 0x804, though. With this changeset, the RK3188 boot removes the TPL (stub) stage and builds a single SPL binary that utilizes the early back-to-bootrom via the boot0-hook. Consequently, the passing of the saved boot params via pmu->os_reg[2] is also removed. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-08-13rockchip: back-to-bootrom: split BACK_TO_BOOTROM for TPL/SPLPhilipp Tomsich
The back-to-bootrom option is rather unfortunately named CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM instead of CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM), we need to rename it. At the same time, we introduce a TPL_ variant of the option to give us finer-grained control over when it should be used. This change is motivated by our RK3368 boot process, which returns to the boot ROM only from the TPL stage, but not from the SPL stage.

2017-04-04rockchip: rk3188: Setup the armclk in splHeiko Stübner
The armclk starts in slow mode (24MHz) on the rk3188, which results in U-Boot startup taking a lot of time (U-Boot itself, but also the rc4 decoding done in the bootrom). With default pmic settings we can always reach a safe frequency of 600MHz which is also the frequency the proprietary loader left the armclk at, without needing access to the systems pmic.
