Simon Glass	2f541aa53c	tlv_eeprom: Return -ENOSYS when system call is not available ... When CMD_TLV_EEPROM is not enabled, use -ENOSYS, which is the correct error code for U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>	2021-04-06 16:33:19 +12:00
Baruch Siach	1c79f2ff88	cmd: add tlv_eeprom command ... Add support for read/write of ONIE "Tlvinfo" EEPROM data format. TLV stands for Type-Length-Value. The data format is described here: https://opencomputeproject.github.io/onie/design-spec/hw_requirements.html#board-eeprom-information-format Based on U-Boot patch from the Open Compute project: ec87e872d4/patches/u-boot/common/feature-sys-eeprom-tlv-common.patch Keep only I2C EEPROM support. Use the generic eeprom driver. Fix checkpatch issues. Add support for multiple EEPROM TLV stores on the same system. This is useful in case of SOM and carrier that both provide ID and hardware configuration information. Add option to enable for SPL. This allows selection of RAM configuration based on EEPROM stored board identification. Signed-off-by: Baruch Siach <baruch@tkos.co.il>	2020-01-21 15:56:15 +01:00
