Pali Rohár 8b3d7ecdfe arm: mvebu: Add support for reading LD0 and LD1 eFuse ... Armada 385 contains 64 lines of HD eFuse and 2 lines of LD eFuse. HD eFuse is used for secure boot and each line is 64 bits long + 1 lock bit. LD eFuse lines are 256 bits long + 1 lock bit. LD 0 line is reserved for Marvell Internal Use and LD 1 line is for General Purpose Data. U-Boot already contains HD eFuse reading and programming support. This patch implements LD eFuse reading support. LD 0 line is mapped to U-Boot fuse bank 64 and LD 1 line to fuse bank 65. LD 0 Marvell Internal Use line seems that was burned in factory with some data and can be read by U-Boot fuse command: => fuse read 64 0 9 LD 1 General Purpose Data line is by default empty and can be read by U-Boot fuse command: => fuse read 65 0 9 Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Marek Behún <marek.behun@nic.cz>		2022-04-21 12:31:36 +02:00
