* x86: Allow a UART to be set up before the FSP is readySimon Glass2015-02-06-0/+4
| | | | | | | | | Since the FSP is a black box it helps to have some sort of debugging available to check its inputs. If the debug UART is in use, set it up after CAR is available. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Remove unnecessary casts and fix comment typosSimon Glass2015-02-06-5/+5

* x86: mmc: Move common FSP functions into a common fileSimon Glass2015-02-06-0/+56
| | | | | | | | | | | | Since these board functions seem to be the same for all boards which use FSP, move them into a common file. We can adjust this later if future FSPs need more flexibility. This creates a generic PCI MMC device. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Make CAR and DRAM FSP code commonSimon Glass2015-02-05-0/+207
| | | | | | | | | For now this code seems to be the same for all FSP platforms. Make it common until we see what differences are required. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Adjust the FSP types slightlySimon Glass2015-02-05-2/+2
| | | | | | | | | | 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.
