[Qemu-devel] [PATCH 18/19] aspeed/smc: inject errors in DMA checksum

2019-05-25 Thread Cédric Le Goater
Emulate read errors in the DMA Checksum Register for high frequencies and optimistic settings of the Read Timing Compensation Register. This will help in tuning the SPI timing calibration algorithm. The values below are those to expect from the first flash device of the FMC controller of a palmett
