2020-07-20x86: mp: Support APs waiting for instructionsSimon Glass
At present the APs (non-boot CPUs) are inited once and then parked ready for the OS to use them. However in some cases we want to send new requests through, such as to change MTRRs and keep them consistent across CPUs. Change the last state of the flight plan to go into a wait loop, accepting instructions from the main CPU. Drop cpu_map since it is not used.

2020-07-17x86: apl: Set the correct boot mode in the FSP-M codeSimon Glass
If there is MRC information we should run FSP-M with a different boot_mode flag since it is supposed to do a 'fast path' through the memory init. Fix this.

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.

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.

2020-07-17x86: Avoid #ifdef with CONFIG_HAVE_ACPI_RESUMESimon Glass
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.

In the future if we have separate symbols for DM_SPI_FLASH and SPL_DM_SPI_FLASH we will not always have function declarations available for some DM calls. This in turn leads to build warnings but not failures as the code isn't used and is discarded at link time. Restructure things to not build code we won't use for TPL anyways.
