2019-10-08spl: pass args to board_return_to_bootromPeng Fan
Pass spl_image and bootdev to board_return_bootrom. i.MX8MN needs the args to let ROM to load images Cc: Simon Glass <sjg@chromium.org> Cc: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Cc: Kever Yang <kever.yang@rock-chips.com> Signed-off-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
2019-07-11arm: spear: Return to BootROM if failing to boot from the main deviceMiquel Raynal
Overload the weak function board_boot_order() so that besides choosing the main boot device, we can fallback on USB boot by returning in the BootROM, eg. if the NOR flash is empty while it was the primary boot medium.

2019-07-11arm: spear: Support returning to BootROMMiquel Raynal
Implement the weak board_return_to_bootrom() function so that when enabling the spl_bootrom.c driver, one can make use of usbboot on spear platforms. All necessary information to return to the BootROM are stored in the BootROM's stack. The SPL stack pointer is reset so we save the BootROM's stack pointer into the SPL .data section.

2019-07-11arm: spear: Drop useless board_init_r callMiquel Raynal
It is clearly stated that board_init_f should *not* call board_init_r. Indeed, board_init_f should return. The code will continue through arch/arm/lib/crt0.S which will do more setup before calling board_init_r.

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>

2015-08-28arm: spear: Move to common SPL infrastructureStefan Roese
The SPL implementation for SPEAr600 is older than the common SPL infrastructure. This patch now moves the SPEAr600 SPL over to the common SPL code. Tested on the only SPEAr board that currently uses SPL in mainline U-Boot, the x600.

2012-07-07SPL: ARM: spear: Add SPL support for SPEAr600 platformStefan Roese
This patch adds SPL support for SPEAr600. Currently only SNOR (Serial NOR) flash support is included. Other boot devices (NAND, MMC, USB ...) may be added with later patches. Tested on the STM SPEAr600 evaluation and x600 SPEAr600 boards. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Amit Virdi <amit.virdi@st.com> Cc: Vipin Kumar <vipin.kumar@st.com>
