x86: fsp: Configure SPI opcode registers before SPI is locked down

2017-08-24T03:00:47Z

Some Intel FSP (like Braswell) does SPI lock-down during the call to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done, it's bootloader's responsibility to configure the SPI controller's opcode registers properly otherwise SPI controller driver doesn't know how to communicate with the SPI flash device. This introduces a Kconfig option CONFIG_FSP_LOCKDOWN_SPI for such FSPs. When it is on, U-Boot will configure the SPI opcode registers before the lock-down.

x86: fsp: Remove the call to set up internal uart in fsp_init()

2017-06-05T00:55:22Z

First of all, it's inappropriate to call setup_internal_uart() in a generic API fsp_init(), as CONFIG_INTERNAL_UART is an option that is only available on BayTrail platform. Secondly even for BayTrail, there is no need to call setup_internal_uart() at all, as Intel FSP will do this for us. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese Reviewed-by: Simon Glass

x86: fsp: Save stack address to CMOS for next S3 boot

2017-05-17T09:11:46Z

At the end of pre-relocation phase, save the new stack address to CMOS and use it as the stack on next S3 boot for fsp_init() continuation function. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Stefan Roese

x86: fsp: Mark memory used by U-Boot as reserved in the E820 table for S3

2017-05-17T09:11:46Z

U-Boot itself as well as everything that is consumed by U-Boot (like heap, stack, dtb, etc) needs to be reserved and reported in the E820 table when S3 resume is on. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Stefan Roese

x86: Store and display previous sleep state

x86: fsp: acpi: Pass different boot mode to FSP init

2017-05-17T09:11:46Z

When ACPI S3 resume is turned on, we should pass different boot mode to FSP init instead of default BOOT_FULL_CONFIG. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Stefan Roese

board_f: Drop setup_dram_config() wrapper

2017-04-05T20:36:51Z

By making dram_init_banksize() return an error code we can drop the wrapper. Adjust this and clean up all implementations. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese

board_f: x86: Use checkcpu() for CPU init

2017-04-05T17:55:09Z

At present we misuse print_cpuinfo() do so CPU init on x86. This is done because it is the next available call after the console is enabled. But several arches use checkcpu() instead. Despite the horrible name (which we can fix), it seems a better choice. Adjust the various x86 CPU implementations to move their init code into checkcpu() and use print_cpuinfo() only for printing CPU info. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese

board_f: x86: Rename x86_fsp_init() to arch_fsp_init()

2017-04-05T17:52:36Z

While x86 is the only user and this could in principle be moved to arch_cpu_init() there is some justification for this being a separate call. It provides a way to handle init which is not CPU-specific, but must happen before the CPU can be set up. Rename the function to be more generic. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese

x86: fsp: Wrap setup_internal_uart() call with CONFIG_INTERNAL_UART

2016-07-12T05:46:01Z

For any FSP-enabled boards that want to enable debug UART support, setup_internal_uart() will be called, but this API is only available on BayTrail platform. Change to wrap it with CONFIG_INTERNAL_UART. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese Reviewed-by: Simon Glass
