| |
+ some people possibly interested in this for the Altera platforms (see below)
Hi all,
This is about moving the cadence qspi driver (which is used on TI, Altera FPGAs and a new Intel SoC) to spi-mem.Vadivel asked me to include some Altera people in the loop (see below), as this is the only platform currently untested, I think.
Right now, I'm not in the position to test this myself as we're currently stuck on an older RT kernel, so I cannot test with HEAD.
Feel free to involve other Intel/Altera if you're interested in that peripheral not being broke for socfpga in one of the next releases :-)

OK, done that. I mainly know them from U-Boot development, so I'm not sure who's responsible for the Linux drivers...
