x86: coral: Show memory config and SKU ID on startup
Provide the model information through sysinfo so that it shows up on boot. For memconfig 4 pins are provided, for 16 combinations. For SKU ID there are two options: - two pins provided in a ternary arrangement, for 9 combinations. - reading from the EC Add a binding doc and drop the unused #defines as well. Example: U-Boot 2021.01-rc5 CPU: Intel(R) Celeron(R) CPU N3450 @ 1.10GHz DRAM: 3.9 GiB MMC: sdmmc@1b,0: 1, emmc@1c,0: 2 Video: 1024x768x32 @ b0000000 Model: Google Coral (memconfig 5, SKU 3) This depends on the GPIO series: http://patchwork.ozlabs.org/project/uboot/list/?series=228126 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
