Subject: [PATCH] efi_selftest: check for RISC-V boot-hartid in FDT
On RISC-V check that the /chosen node has a boot-hartid property.
To run the test configure with CONFIG_CMD_BOOTEFI_SELFTEST=y and issue
setenv efi_selftest device tree
setenv serial# myserial
bootefi selftest
If the test succeeds, it reports the boot-hartid, e.g.
boot-hartid: 1
