Hello, We have been seeing a squashfs corruption on the witherspoon-bmc machine for quite some time. It boots but quickly after boot corruption errors start to fill the console. This machine has two BMC chips with UBIfs on them. The romulus-bmc machine has a similar problem when both PNOR are enabled.
After some investigation, it appeared that the SPI transfers on the two chips were getting mixed and after more investigation, the User mode select/unselect scheme of the Aspeed SMC model proved to be broken. It's been there since the right beginning of the model. Here is a fix. Kudos to Andrew J. for the time he spent on this and Andrew G. for his patience. I pushed the code on my github branch aspeed-5.0 for more testing. Thanks, C.
