2019-10-08x86: Add a common function to set CPU thermal targetSimon Glass

2019-10-08x86: pci: Drop the first parameter in pci_x86_r/w_config()Simon Glass
This parameter is needed by the PCI driver-mode interface but is always NULL on x86. There are a number of calls to this function so it makes sense to minimise the parameters. Adjust the x86 function to omit the first parameter, and introduce stub functions to handle the conversion.

2019-10-08x86: Add more comments to the start-up codeSimon Glass
The full start-up sequence (TPL->SPL->U-Boot) can be a bit confusing since each phase has its own 'start' file. Add comments to explain this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08x86: Change condition for using CARSimon Glass
At present we assume that CAR (Cache-as-RAM) is used if HOBs (Hand-off blocks) are not, since HOBs typically indicate that an FSP is in use, and FSPs handle the CAR init. However this is a bit indirect, and for FSP2 machines which use their own CAR implementation (such as apollolake) but use the FSP for other functions, the logic is wrong. To fix this, add a dedicated Kconfig option to indicate when CAR is used.

2019-10-08x86: fsp: Save usable RAM and hob_list in the handoff areaSimon Glass
The useable RAM is calculated when the RAM is inited. Save this value so that it can be easily used in U-Boot proper. Also save a pointer to the hob list so that it is accessible (before relocation only) in U-Boot proper. This avoids having to scan it in SPL, for everything U-Boot proper might need later.

2019-10-08x86: spl: Move broadwell-specific code out of generic x86 splSimon Glass
When TPL is running, broadwell needs to do different init from SPL. There is no need for this code to be in the generic x86 SPL file, so move it to arch_cpu_init(). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08x86: spl: Reduce priority of the basic SPL image loaderSimon Glass
This image loader works on systems where the flash is directly mapped to the last part of the 32-bit address space. On recent Intel systems (such as apollolake) this is not the case. Reduce the priority of this loader so that another one can override it. While we are here, rename the loader to BOOT_DEVICE_SPI_MMAP since BOOT_DEVICE_BOARD is not very descriptive.
