* x86: fsp: Set up init runtime buffer in update_fsp_configs()Bin Meng2016-01-131-1/+3
| | | | | | | | | fsp_init() runtime buffer parameter might be different across different platforms. Move this to update_fsp_configs(). Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
* x86: fsp: Move struct fspinit_rtbuf definition to chipset headerBin Meng2016-01-132-16/+0
| | | | | | | | | | | | | All FSP spec v1.0 complaint FSP binary uses struct fspinit_rtbuf as defined by the 1.0 spec, however there are FSPs that does not follow 1.0 spec (possible due to that FSP predates the 1.0 spec), and future FSP binary that is complaint to v1.1 spec defines an optional paltform-specific runtime data in the struct fspinit_rtbuf. Hence move the definition to chipset header. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
* x86: fsp: Rename update_fsp_upd() and change its signatureBin Meng2016-01-131-3/+3
| | | | | | | | | | | To support platform-specific configurations (might not always be UPD on some platform), use a better name update_fsp_configs() and accepct struct fsp_config_data as its parameter so that platform codes can handle whatever configuration data for that FSP.

* x86: fsp: Rename shared_data to fsp_config_dataBin Meng2016-01-132-7/+11
| | | | | | | | | | | | FSP has several config data like UPD, HDA verb table which can be overridden or provided by bootloader. Currently in U-Boot only UPD is handled via struct shared_data. To accommodate any platform, we rename shared_data to fsp_config_data and move the definition from common place fsp_support.h to platform-specific place fsp_configs.h.

* x86: fsp: Avoid cast stack_top in struct shared_dataBin Meng2016-01-132-2/+2
| | | | | | | | | Declare stack_top as u32 in struct shared_data and struct common_buf so that we can avoid casting in fsp_init(). Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
* x86: fsp: Simplify fsp_continue()Bin Meng2016-01-131-3/+1
| | | | | | | | | There is no need to pass shared_data to fsp_continue() so we can remove unnecessary codes that simplifies the function a lot. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
* x86: Drop FSP error defines and use EFI insteadSimon Glass2015-08-141-11/+0
| | | | | | | | Now that we have an efi.h header we can use that for FSP error defines. Drop the FSP ones. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Split out fsp_init_phase_pci() code into a new functionSimon Glass2015-08-141-0/+7
| | | | | | | | | | | This code may be useful for boards that use driver model for PCI. Note: It would be better to have driver model automatically call this function somehow. However for now it is probably safer to have it under board control. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* efi: Add start-up library codeSimon Glass2015-08-051-57/+2
| | | | | | | | | | | When running as an EFI application, U-Boot must request memory from EFI, and provide access to the boot services U-Boot needs. Add library code to perform these tasks. This includes efi_main() which is the entry point from EFI. U-Boot is built as a shared library. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Adjust the FSP types slightlySimon Glass2015-02-052-3/+7
| | | | | | | | | | To avoid casts, find_fsp_header() should return a pointer. Add asmlinkage to two API functions which use that convention. UPD_TERMINATOR is common so move it into a common file.
