[PATCH] aspeed_defconfig: Enable SHMEM and TMPFS

[Andrew Jeffery]

Without enabling these options we get strange behaviour under qemu,
where it appears uevents aren't generated to create device nodes for
ttyS{0,4,5}. As a consequence we don't receive a getty on the console.

Cédric narrowed down the list of options initially at [1],
and with a patch to the qemu timer model[2] we can retain the
CONFIG_NO_HZ_IDLE=y configuration.
