x86: fsp: Only FSP2 has INIT_PHASE_END_FIRMWARE

2021-08-02T16:01:38+00:00

For FSP1, there is no such INIT_PHASE_END_FIRMWARE. Move board_final_cleanup() to fsp2 directory.

x86: fsp: Don't program MTRR for DRAM for FSP1

2021-08-02T16:01:29+00:00

There are several outstanding issues as to why this does not apply to FSP1: * For FSP1, the system memory and reserved memory used by FSP are already programmed in the MTRR by FSP. * The 'mtrr_top' mistakenly includes TSEG memory range that has the same RES_MEM_RESERVED resource type. Its address is programmed and reported by FSP to be near the top of 4 GiB space, which is not what we want for SDRAM. * The call to mtrr_add_request() is not guaranteed to have its size to be exactly the power of 2. This causes reserved bits of the IA32_MTRR_PHYSMASK register to be written which generates #GP. For FSP2, it seems this is necessary as without this, U-Boot boot process on Chromebook Coral goes very slowly.

x86: fsp: Don't enable FSP graphics if booted from coreboot

2021-03-27T02:04:30+00:00

This driver cannot work when booted from coreboot, since the FSP information is not available. Disable it in that case, so that the coreboot video driver can be used instead. Signed-off-by: Simon Glass

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. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

dm: treewide: Rename ..._platdata variables to just ..._plat

Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass

x86: fsp: Adjust calculations for MTRR range and DRAM top

2020-11-06T01:51:33+00:00

At present the top of available DRAM is the same as the top of the range of the low-memory MTRR. In fact, U-Boot is allowed to use memory up until the start of the FSP reserved memory. Use that value for low_end, since it makes more memory available. Keep the same calculation as before for mtrr_top, i.e. the top of reserved memory. A side-effect of this change is that the E820 tables have a single entry that extends from the bottom of the memory used by U-Boot to the bottom of the FSP reserved memory. This includes the bloblist, if ACPI tables are placed there. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Silence some logging statements

2020-11-06T01:51:32+00:00

Quite a few log_info() calls are included in the x86 code which should use log_debug() instead. Convert them to reduce unwanted output. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add a way to add to the e820 memory table

Some boards want to reserve extra regions of memory. Add a 'chosen' property to support this. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Notify the FSP of the 'end firmware' event

2020-09-25T03:27:22+00:00

Send this notification when U-Boot is about to boot into Linux, as requested by the FSP. Currently this causes a crash with the APL FSP, so leave it disabled for now. Signed-off-by: Simon Glass
