u-boot.git/arch/x86/include/asm/itss.h, branch master Unnamed repository; edit this file 'description' to name the repository. x86: Move priv/plat structs for intel_common to headers 2021-01-05T19:24:41+00:00 Simon Glass sjg@chromium.org 2020-12-19T17:39:58+00:00 f6257f7914858cd99219feb3185c679137857b60 With the new of-platdata, these need to be available to dt_platdata.c so must be in header files. Move them. Signed-off-by: Simon Glass <sjg@chromium.org>

x86: apl: Fix save/restore of ITSS priorities 2020-07-17T06:32:24+00:00 Simon Glass sjg@chromium.org 2020-07-17T03:22:30+00:00 b95611f67e709f8c98c1a31714dc941d436c0d5c 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.
