x86: Clean up the FSP support codes

2014-12-19T00:26:08Z

This is the follow-on patch to clean up the FSP support codes: - Remove the _t suffix on the structures defines - Use __packed for structure defines - Use U-Boot's assert() - Use standard bool true/false - Remove read_unaligned64() - Use memcmp() in the compare_guid() - Remove the cast in the memset() call - Replace some magic numbers with macros - Use panic() when no valid FSP image header is found - Change some FSP utility routines to use an fsp_ prefix - Add comment blocks for asm_continuation and fsp_init_done - Remove some casts in find_fsp_header() - Change HOB access macros to static inline routines - Add comments to mention find_fsp_header() may be called in a stackless environment - Add comments to mention init(¶ms) in fsp_init() cannot be removed Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: move arch-specific asmlinkage to

2014-12-15T14:22:53Z

Commit 65dd74a674d6 (x86: ivybridge: Implement SDRAM init) introduced x86-specific asmlinkage into arch/x86/include/asm/config.h. Commit ed0a2fbf14f7 (x86: Add a definition of asmlinkage) added the same macro define again, this time, into include/common.h. (Please do not add arch-specific stuff to include/common.h any more; it is already too cluttered.) The generic asmlinkage is defined in . If you want to override it with an arch-specific one, the best way is to add it to like Linux Kernel. Signed-off-by: Masahiro Yamada Cc: Simon Glass Tested-by: Simon Glass

x86: Add a simple command to show FSP HOB information

2014-12-14T05:32:06Z

FSP builds a series of data structures called the Hand-Off-Blocks (HOBs) as it progresses through initializing the silicon. These data structures conform to the HOB format as described in the Platform Initialization (PI) specification Volume 3 Shared Architectual Elements specification, which is part of the UEFI specification. Create a simple command to parse the HOB list to display the HOB address, type and length in bytes. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Support Intel FSP initialization path in start.S

2014-12-14T05:32:05Z

Per Intel FSP architecture specification, FSP provides 3 routines for bootloader to call. The first one is the TempRamInit (aka Cache-As-Ram initialization) and the second one is the FspInit which does the memory bring up (like MRC for other x86 targets) and chipset initialization. Those two routines have to be called before U-Boot jumping to board_init_f in start.S. The FspInit() will return several memory blocks called Hand Off Blocks (HOBs) whose format is described in Platform Initialization (PI) specification (part of the UEFI specication) to the bootloader. Save this HOB address to the U-Boot global data for later use. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Clean up asm-offsets

2014-12-14T05:32:04Z

Move GD_BIST from lib/asm-offsets.c to arch/x86/lib/asm-offsets.c as it is x86 arch specific stuff. Also remove GENERATED_GD_RELOC_OFF which is not referenced anymore. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Add support for running option ROMs natively

2014-11-25T13:38:57Z

On x86 machines we can use an emulator to run option ROMS as with other architectures. But with some additional effort (mostly due to the 16-bit nature of option ROMs) we can run them natively. Add support for this. Signed-off-by: Simon Glass

x86: Refactor interrupt_init()

2014-11-25T13:34:02Z

Rename interrupt_init() in arch/x86/lib/pcat_interrupts.c to i8259_init() and create a new interrupt_init() in arch/x86/cpu/interrupt.c to call i8259_init() followed by a call to cpu_init_interrupts(). Signed-off-by: Bin Meng Acked-by: Simon Glass Tested-by: Simon Glass

x86: Call cpu_init_interrupts() from interrupt_init()

2014-11-25T13:34:02Z

Currently cpu_init_interrupts() is called from cpu_init_r() to setup the interrupt and exception of the cpu core, but at that time the i8259 has not been initialized to mask all the irqs and remap the master i8259 interrupt vector base, so the whole system is at risk of being interrupted, and if interrupted, wrong interrupt/exception message is shown.
