2017-01-24ARM: vf610m4: defconfig: enable EXT4 filesystemafzal mohammed
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). Signed-off-by: afzal mohammed <afzal.mohd.ma@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2015-05-20ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4Stefan Agner
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.
