[PATCH 3/3] aspeed/smc: Fix number of dummy cycles for FAST_READ_4 command

2020-02-03 Thread Guenter Roeck
The Linux kernel recently started using FAST_READ_4 commands. This results in flash read failures. At the same time, the m25p80 emulation is seen to read 8 more bytes than expected. Adjusting the expected number of dummy cycles to match FAST_READ fixes the problem. Signed-off-by: Guenter Roeck --
