2020-07-17x86: Store the coreboot table address in global_dataSimon Glass
At present this information is used to locate and parse the tables but is not stored. Store it so that we can display it to the user, e.g. with the 'bdinfo' command. Note that now the GD_FLG_SKIP_LL_INIT flag is set in get_coreboot_info(), so it is always set when booting from coreboot.

2020-07-17x86: apl: Fix save/restore of ITSS prioritiesSimon Glass
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.

The Intel Non-High-Definition-Audio Link Table (NHLT) table describes the audio codecs and connections in a system. Various devices can contribute information to produce the table. Add functions to allow adding to the structure that is eventually written to the ACPI tables. Also add the device-tree bindings. Signed-off-by: Simon Glass <sjg@chromium.org>

With DDR4, Intel SOCs take quite a long time to init their memory. During this time, if the user is watching, it looks like SPL has hung. Add a message in this case. This works by adding a return code to fspm_update_config() that indicates whether MRC data was found and a new property to the device tree. Also add one more debug message while starting.

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.
