arm: init: save previous bootloader data

2022-04-04T18:53:26+00:00

When u-boot is used as a chain-loaded bootloader (replacing OS kernel),
previous bootloader leaves data in RAM, that can be reused.

For example, on recent arm linux system, when chainloading u-boot,
there are initramfs and fdt in RAM prepared for OS booting. Initramfs
may be modified to store u-boot's payload, thus providing the ability to
use chainloaded u-boot to boot OS without any storage support.

Two config options added:
- SAVE_PREV_BL_INITRAMFS_START_ADDR
  saves initramfs start address to 'prevbl_initrd_start_addr' environment
  variable
- SAVE_PREV_BL_FDT_ADDR
  saves fdt address to 'prevbl_fdt_addr' environment variable

event: Convert arch_cpu_init_dm() to use events

2022-03-10T13:28:36+00:00

Instead of a special function, send an event after driver model is inited
and adjust the boards which use this function.

event: Convert misc_init_f() to use events

2022-03-10T13:28:36+00:00

This hook can be implmented using events, for the three boards that
actually use it.

Add the event type and event handlers. Drop CONFIG_MISC_INIT_F since we
can just use CONFIG_EVENT to control this. Since sandbox always enables
CONFIG_EVENT, we can drop the defconfig lines there too.

common: board_r: move init_addr_map() to init.h

2022-01-18T13:31:02+00:00

asm/mmu.h include is currently guarded by CONFIG_ADDR_MAP ifdef because
the header is only present on arm and powerpc. In order to remove the
dependency on this header and the associated ifdef, move init_addr_map()
declaration to init.h, since it is only called during the common init
sequence.

efi: Fix ll_boot_init() operation with the app

2021-12-31T05:45:01+00:00

This should return false when the EFI app is running, since UEFI has done
the required low-level init. Fix it.

bdinfo: Rename function names to be clearer

2021-02-03T10:38:41+00:00

At present we have bdinfo_print_num() to print unsigned long numbers.
We also have print_phys_addr() which accept numbers that might be
64-bit on a 32-bit platform.

Rename these 2 functions to be clearer:

bdinfo_print_num() => bdinfo_print_num_l()
print_phys_addr()  => bdinfo_print_num_ll()

While we are here, make bdinfo_print_num_ll() public so that it can
be used outside cmd/bdinfo.c in the future.

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.
