* x86: Move common FSP code into a common locationSimon Glass2015-02-051-1/+1

* x86: fsp: Drop get_hob_type() and get_hob_length()Bin Meng2015-01-131-3/+3
| | | | | | | | | | | These two are not worth having separate inline functions as they are really simple, so drop them. Also changed 'type' parameter of fsp_get_next_hob() from u16 to uint.

* x86: Simplify the fsp hob access functionsBin Meng2015-01-121-8/+8
| | | | | | | | | Remove the troublesome union hob_pointers so that some annoying casts are no longer needed in those hob access routines. This also improves the readability. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Clean up the FSP support codesBin Meng2014-12-181-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | 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(&params) in fsp_init() cannot be removed Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Add a simple command to show FSP HOB informationBin Meng2014-12-131-0/+67
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 <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
