7f55c733b6 firmware: Drop FIRMWARE_IN_KERNEL Kconfig option
It doesn't actually do anything.  Merge its help text into
EXTRA_FIRMWARE.

Fixes: 5620a0d1aa ("firmware: delete in-kernel firmware")
Fixes: 0946b2fb38 ("firmware: cleanup FIRMWARE_IN_KERNEL message")

5aaac4278a ARM: vf610m4: defconfig: enable EXT4 filesystem
Enable EXT4_FS to have rootfs in EXT[2-4].

Other changes are result of savedefconfig keeping minimal config (even
without enabling EXT4_FS, these would be present).

b4423bb834 ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4
Add defconfig for Linux on Vybrid (vf610) on the secondary Cortex-
M4 CPU. The use of a XIP image has been tested which needs to be
loaded (e.g. using the custom m4boot loader) to the end of the
available RAM at address 0x8f000000. The Cortex-M4 has a code-alias
which makes sure that the instructions get fetched through the code
bus (alias starts at 0x00800000 => 0x80800000 in system address).
Hence, to get optimal performance, use 0x0f000000 as XIP_PHYS_ADDR.
This address is additionally shifted by the length of the minimal
loader which is inserted by m4boot. Currently, this offset is 0x80.

The standard DRAM base address is configured to 0x8C000000, which
gives the Cortex-M4 48MiB of RAM.
