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
encounters RAW images, express this same functionality as a positive
option enabling support for RAW images: CONFIG_SPL_RAW_IMAGE_SUPPORT

Also move uses of this to defconfigs.

spl: Add spl_early_init()

2017-03-16T22:03:43+00:00

At present malloc_base/_limit/_ptr are not initialised in spl_init() when
we call spl_init() in board_init_f(). This is due to a recent change aimed
at avoiding overwriting the malloc area set up on some boards by
spl_relocate_stack_gd().

However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
skip setting up the memory area in spl_init() which is obviously wrong.

To fix this, add a new function spl_early_init() which can be called in
board_init_f().

SPL: make struct spl_image 64-bit safe

2017-01-04T15:37:41+00:00

Since entry_point and load_addr are addresses, they should be
represented as longs to cover the whole address space and to avoid
warning when compiling the SPL in 64-bit.
Also adjust debug prints to add the 'l' specifier, where needed.

spl: Add a name to the SPL load-image methods

2016-12-09T13:40:13+00:00

It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.

The name is only available if we have libcommon support (i.e can use
printf()).
