2019-12-15x86: Set the DRAM banks to reflect real locationSimon Glass
At present with fsp a single DRAM bank is added which extends to the whole size of memory. However there is typically only 2GB of memory available below the 4GB boundary, and this is what is used by U-Boot while running in 32-bit mode. Scan the tables to set the banks correct.

This should take account of the end of the new cache record since a record cannot extend beyond the end of the flash region. This problem was not seen before due to the alignment of the relatively small amount of MRC data. But with Apollo Lake the MRC data is about 45KB, even if most of it is zeroes.

2019-12-15x86: timer: use a timer base of 0Simon Glass
On x86 platforms the timer is reset to 0 when the SoC is reset. Having this as the timer base is useful since it provides an indication of how long it takes before U-Boot is running. When U-Boot sets the timer base to something else, time is lost and we no-longer have an accurate account of the time since reset. This particularly affects bootstage. Change the default to not read the timer base, leaving it at 0. Add an option for when U-Boot is the secondary bootloader.

2019-12-15x86: spi: Add helper functions for Intel Fast SPISimon Glass
Most x86 CPUs use a mechanism where the SPI flash is mapped into the very top of 32-bit address space, so that it can be executed in place and read simply by copying from memory. For an 8MB ROM the mapping starts at 0xff800000. However some recent Intel CPUs do not use a simple 1:1 memory map. Instead the map starts at a different address and not all of the SPI flash is accessible through the map. This 'Fast SPI' feature requires that U-Boot check the location of the map. It is also possible (optionally) to read from the SPI flash using a driver. Add support for booting from Fast SPI. The memory-mapped version is used by both TPL and SPL on Apollo Lake. In respect of a SPI flash driver, the actual SPI driver is ich.c - this just adds a few helper functions and definitions. This is used by Apollo Lake.

2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).

2019-12-10riscv: add option to wait for ack from secondary harts in smp functionsLukas Auer
Add a wait option to smp_call_function() to wait for the secondary harts to acknowledge the call-function request. The request is considered to be acknowledged once each secondary hart has cleared the corresponding IPI. As part of the call-function request, the secondary harts invalidate the instruction cache after clearing the IPI. This adds a delay between acknowledgment (clear IPI) and fulfillment (call function) of the request. We want to use the acknowledgment to be able to judge when the request has been completed. Remove the delay by clearing the IPI after cache invalidation and just before calling the function from the request.

2019-12-10riscv: increase stack size to avoid a stack overflow during distro bootLukas Auer
This fixes a problem, where booting Linux using distro boot will sometimes lead to an invalid instruction exception on the main hart. The secondary harts are not affected and boot Linux successfully. The root cause of this problem is a stack overflow on the main hart. With distro boot, the current default stack size of 8KiB on RISC-V is not sufficient and will cause a stack overflow. The stacks are allocated sequentially. In the case of a stack overflow the stack of the main hart can reach into that of another hart and be corrupted. The stack overflow previously did not cause any problems, because only stack frames, which are not used anymore since the hart enters Linux, were corrupted. Starting with GCC 9, the stack usage has decreased. Now, only the most recent stack frame overflows into the stack of a secondary hart and is corrupted. The illegal instruction exception is caused by the secondary hart overwriting the return address in the stack frame of the main hart with an address that does not include valid code. Increase the default stack size of each hart to 16KiB to avoid this problem.

The commit 1b42ab3eda8a ("ARM: DRA7: Fixup DSPEVE, IVA and GPU clock frequencies based on OPP") added the core logic to update the kernel device-tree blob to adjust the DSP, IVA and GPU DPLL clocks based on a one-time OPP choice selected in U-Boot for most of the DRA7xx/AM57xx family of SoCs. The DSPs on DRA76xP/DRA77xP SoCs (DRA76x ACD package SoCs) though provide a higher performance and can run at a higher clock frequency of 850 MHz at OPP_HIGH instead of 750 MHz. Fix up the logic to use the correct clock rates on these SoCs. Note that this higher clock rate is not applicable to other Jacinto 6 Plus SoCs (DRA75xP/DRA74xP SoCs or AM574x SoCs) that follow the ABZ package.
