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

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

x86: Allow writing tables to fail

2020-11-05T06:58:45+00:00

At present write_tables() can fail but does not report this problem to its caller. Fix this by changing the return type. 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

x86: mp: Park CPUs before running the OS

2020-07-20T01:46:46+00:00

With the new MP features the CPUs are no-longer parked when the OS is run. Fix this by calling a special function to park them, just before the OS is started. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

x86: cpu: Remove unnecessary #ifdefs

2020-07-20T01:46:44+00:00

Drop some #ifdefs that are not needed or can be converted to compile-time checks. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

x86: Rename board_final_cleanup() to board_final_init()

2020-07-17T06:32:24+00:00

This function sounds like something that is called when U-Boot is about to jump to Linux. In fact it is an init function. Rename it to reduce confusion. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Wolfgang Wallner

x86: apl: Fix save/restore of ITSS priorities

2020-07-17T06:32:24+00:00

The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Wolfgang Wallner

x86: Avoid #ifdef with CONFIG_HAVE_ACPI_RESUME

2020-07-17T06:32:24+00:00

At present this enables a few arch-specific members of the global_data struct which are otherwise not part of the struct. As a result we have to use #ifdef in various places. The cost of always having these in the struct is small. Adjust things so that we can use compile-time code instead of #ifdefs. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
