Heinrich Schuchardt c48e9f310b riscv: restore global data pointer in trap handler ... The gp register is used to store U-Boot's global data pointer. We should not assume that an UEFI application leaves the gp register unchanged as the UEFI specifications does not define who is the owner of the gp and tp registers. So the following sequence should be followed in the trap handler: * save the caller's gp register * restore the global data pointer * serve interrupts or print crash dump and reset * restore the caller's gp register Cc: Abner Chang <abner.chang@hpe.com> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Bin Meng <bin.meng@windriver.com> Reviewed-by: Rick Chen <rick@andestech.com>		2020-09-28 12:20:19 +02:00
