bootstage: Eliminate when not enabled

2021-07-07T14:17:54+00:00

When we do not have bootstage enabled, rather than include an empty
dummy function, we just don't reference it.  This saves us space in some
tight builds.  This also shows a few cases where show_boot_progress was
incorrectly guarded before.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

CONFIG_NR_DRAM_BANKS: Remove unreferenced code as its always defined

2020-08-26T07:19:16+00:00

Since commit 86cf1c82850f ("configs: Migrate CONFIG_NR_DRAM_BANKS") &
commit 999a772d9f24 ("Kconfig: Migrate CONFIG_NR_DRAM_BANKS"),
CONFIG_NR_DRAM_BANKS is always defined with a value (4 is default).
It makes no sense to still carry code that is guarded with
"#ifndef CONFIG_NR_DRAM_BANKS" (and similar). This patch removes
all these unreferenced code paths.

spl: fix stack usage check if gd is not initialized

2020-01-10T15:25:13+00:00

Most platforms do not set up gd->start_addr_sp in SPL. Since this is
required for CONFIG_SPL_SYS_REPORT_SACK_F_USAGE to work correctly, set
up gd->start_addr_sp in SPL to the value passed to
board_init_f_init_reserve if it is not set yet.

spl: implement stack usage check

2019-08-11T20:43:41+00:00

This implements a stack usage check in SPL.

Many boards start up SPL to run code + data from one common, rather small
SRAM. To implement a sophisticated SPL binary size limit on such boards,
the stack size (as well as malloc size and global data size) must be
subtracted from this SRAM size.

However, to do that properly, the stack size first needs to be known.

This patch adds a new Kconfig option:
- SPL_SYS_REPORT_STACK_F_USAGE: memset(0xaa) the whole area of the stack
  very early and check stack usage based on this constant later before the
  stack is switched to DRAM

Initializing the stack and checking it is implemented in weak functions,
in case a board does not use the stack as saved in gd->start_addr_sp.

spl: Add support for passing handoff info to U-Boot proper

2018-11-26T13:25:37+00:00

There is some basic informaton that SPL normally wants to pass through to
U-Boot, such as the SDRAM size and bank information.

Mkae use of the new bloblist structure for this. Add a new 'handoff' blob
which is set up in SPL and passed to U-Boot proper. Also adda  test for
sandbox_spl that checks that this works correctly and a new 'sb' command
to show the information passed from SPL.
