Hmmm for some reason the previous replies didn't get picked up by
patchwork, so I'm replying with my comment again for the public
record.
In this case the eSPI controller driver is buggy and needs to be
fixed. If the hardware can only support small transfers, then it is
the responsibilty of t

NAK.
We went over this before.
The bug is in your SPI master controller driver,
and the fix there involves mapping large reads
into multiple s
For Freescale's eSPI controller, the max transaction length one time
is limitted by the SPCOM[TRANSLEN] field which is 0x. When used
mkfs.ext2 command to create ext2 filesystem on the flash, the read
length will exceed the max value of the SPCOM[TRANSLEN] field, so
change the read function to r
