Hi All
For a large number of boards running coreboot (reported on CML, TGL, ADL,
SKL and APL), a change in the last few months has caused an indefinite hang.
For the last three years, coreboot has used a default value of 1000
for gEfiMdeModulePkgTokenSpaceGuid.PcdSdMmcGenericTimeoutValue, but to
workaround the hang, this value had to be changed to 10000.
The new value will get the device booting, but on a smaller selection of
boards, USB devices are not visible to edk2 (either in the EFI Shell, Debug
output or Boot Manager). They function normally in the OS, and the debug
output is below.
I don't suppose anyone would have a hunch as to the cause of this problem?
Many thanks
Sean
