x86/coreboot: Exclude memory regions starting above 4GB

2026-02-16T18:00:42+00:00

This commit updates the RAM region filtering logic in
board_get_usable_ram_top() to skip any memory regions whose start address
is above 4GB. Previously, only the end address was capped at 4GB, but
regions entirely above this threshold were still considered.

Typically, the following memory map entries would cause
board_get_usable_ram_top() to return 0x100000000, which is incorrect.

    start=00000000, end=00001000, type=16
    start=00001000, end=000a0000, type=1
    start=000a0000, end=000f6000, type=2
    start=000f6000, end=000f7000, type=16
    start=000f7000, end=00100000, type=2
    start=00100000, end=6f170000, type=1
    start=6f170000, end=70000000, type=16
    start=70000000, end=80800000, type=2
    start=e0000000, end=f8000000, type=2
    start=fa000000, end=fc000000, type=2
    start=fc800000, end=fc880000, type=2
    start=fd800000, end=fe800000, type=2
    start=feb00000, end=feb80000, type=2
    start=fec00000, end=fed00000, type=2
    start=fed20000, end=fed80000, type=2
    start=feda1000, end=feda2000, type=2
    start=fedc0000, end=fede0000, type=2
    start=100000000, end=102400000, type=2
    start=102400000, end=47f800000, type=1
    start=4000000000, end=4020000000, type=2

By adding a check to continue the loop if the region's start address
exceeds 0xffffffffULL, the function now properly ignores regions that are
not usable in 32-bit address space.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

global: Make include

2024-05-06T21:07:48+00:00

This follows the example of RISC-V where  includes
 directly as "gd" includes a reference to bd_info already
and so the first must include the second anyhow. We then remove
 from all of the places which include references to "gd"
an so have  already.

common: return type board_get_usable_ram_top

2023-08-15T16:21:17+00:00

board_get_usable_ram_top() returns a physical address that is stored in
gd->ram_top. The return type of the function should be phys_addr_t like the
current type of gd->ram_top.

board_f: Fix types for board_get_usable_ram_top()

2022-09-23T19:12:42+00:00

Commit 37dc958947ed ("global_data.h: Change ram_top type to phys_addr_t")
changed type of ram_top member from ulong to phys_addr_t but did not
changed types in board_get_usable_ram_top() function which returns value
for ram_top.

So change ulong to phys_addr_t type also in board_get_usable_ram_top()
signature and implementations.

It is possible to boot U-Boot for chromebook_coral either 'bare metal' or

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.
