2020-05-19common: Drop net.h from common headerSimon Glass1-0/+1
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-01-18common: Move hang() to the same header as panic()Simon Glass1-0/+1
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

2019-05-01rockchip: use 'arch-rockchip' as header file pathKever Yang1-2/+2
Rockchip use 'arch-rockchip' instead of arch-$(SOC) as common header file path, so that we can get the correct path directly. Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2017-11-22rockchip: add support for enter to bootrom download modeAndy Yan1-2/+45
Rockchip bootrom will enter download mode if it returns from spl/tpl with a non-zero value and couldn't find a valid image in the backup partition. This patch provide a method to instruct the system to back to bootrom download mode by checking the BROM_DOWNLOAD_FLAG register. As the bootrom download function relys on some modules such as interrupts, so we need to back to bootrom as early as possbile before the tpl/spl code override the interrupt configurations.

2017-11-22rockchip: back-to-bootrom: allow passing a cmd to the bootromPhilipp Tomsich1-2/+2
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>
2017-11-22rockchip: back-to-bootrom: replace assembly-implementation with C-codePhilipp Tomsich1-1/+51
The back-to-bootrom implementation for Rockchip has always relied on the stack-pointer being valid on entry, so there was little reason to have this as an assembly implementation. This provides a new C-only implementation of save_boot_params and back_to_bootrom (relying on setjmp/longjmp) and removes the older assembly-only implementation.

2017-08-13rockchip: back-to-bootrom: simplify the #ifdef-check for LIBCOMMON in TPL/SPLPhilipp Tomsich1-2/+2
With the finer-grained control over LIBCOMMON_SUPPORT for TPL/SPL (i.e. with the newly introduced distinction between TPL_LIBCOMMON_SUPPORT and SPL_LIBCOMMON_SUPPORT), we can simplify the #ifdef-check to simply use CONFIG_IS_ENABELD.

2017-04-18rockchip: Print a message when returning to the bootromSimon Glass1-0/+16
At present if the return to bootrom fails (e.g. because you are not using the Rockchip's bootrom's pointer table in MMC) then the board prints SPL message and hangs. Print a message first if we can, to help in understanding what happened when it hangs.
