SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

spl: spl_mmc: provide one weak function spl_boot_partition

2018-04-07T00:45:28+00:00

The spl_boot_partition function has been added in order to have
the possibility to boot on a same binary from different mmc devices
with different partitions.

By default keep the current behavior, SPL use the partition defined
by CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION.

binman: Add binman symbol support to SPL

2017-12-13T02:53:45+00:00

Allow SPL to access binman symbols and use this to get the address of
U-Boot. This falls back to CONFIG_SYS_TEXT_BASE if the binman symbol
is not available.

spl: change load_addr and entry_point to uintptr_t

2017-11-25T23:39:07+00:00

Mainly a stylistic change: convert the load_addr and entry_point
fields of struct spl_image_info to uintptr_t (from ulong).

spl: add a fdt_addr field to spl_image_info

2017-11-25T23:39:06+00:00

When loading a full U-Boot with detached device-tree using the SPL FIT
backend, we should store the address of the FDT loaded as part of the
SPL image info: this allows us to fixup the FDT with additional info
we may want to propagate onward.

spl: fix assignment of board info to global data

2017-10-09T15:48:44+00:00

Commit 15eb1d43bf47 ("spl: reorder the assignment of board info to
global data") intended to move assignment of board info earlier,
into board_init_r(). However, function preload_console_init() is
called either from spl_board_init() or from board_init_f(). For the
latter case, the board info assignment is much earlier than proposed
board_init_r(). Create a new function to fill gd->bd and call this
function when needed.

spl: add a 'return to bootrom' boot method

2017-08-13T15:12:19+00:00

Some devices (e.g. the RK3368) have only limited SRAM, but provide
support for loading the next boot stage after our SPL performs basic
setup (e.g. DRAM).

For target systems like these, we add a boot device BOOTROM that will
invoke a board-specific hook to return to the bootrom (if supported).

spl: add support to booting with ATF

2017-05-15T14:38:09+00:00

ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation
about ATF at: https://github.com/ARM-software/arm-trusted-firmware

SPL is considered as BL2 in ATF terminology, it needs to load other parts
of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to
prepare the parameter for BL31 which including entry and image information
for all other images. Then the SPL handle PC to BL31 with the parameter,
the BL31 will do the rest of work and at last get into U-Boot(BL33).

This patch needs work with patches from Andre for SPL support multi
binary in FIT.

The entry point of bl31 and bl33 are still using hard code because we
still can not get them from the FIT image information.

spl: make image arg or fdt blob address reconfigurable

2017-05-08T15:38:40+00:00

At present fdt blob or argument address being passed to kernel is fixed at
compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from
different media like nand, nor flash are copied to the address pointed
by the macro.
The problem is, it makes args/fdt blob compulsory to copy which is not required
in cases like for NOR Flash. This patch removes this limitation.

spl: Convert CONFIG_SPL_ABORT_ON_RAW_IMAGE into a positive option

2017-03-18T18:28:50+00:00

CONFIG_SPL_ABORT_ON_RAW_IMAGE causes SPL to abort and move on when it

Also move uses of this to defconfigs.
