The idea is to increase compatibility with "real" firmware images where only the bare minimum of drivers is compiled in. The series is structured as follows: Patches 1-5 perform some general cleanup which paves the way for the rest of the series. Patches 6-9 add -pflash handling where memory-mapped flash can be added on user's behalf. That is, the flash memory region in the eLBC is only added if the -pflash argument is supplied. Note that the cfi01 device model becomes stricter in checking the size of the emulated flash space. Patches 10-13 add a new device model - the Freescale eSDHC - to the e500 boards which was missing so far. User documentation is also added as the new features become available. Tesing done: * `qemu-system-ppc -M ppce500 -cpu e500mc -m 256 -kernel uImage -append "console=ttyS0 rootwait root=/dev/mtdblock0 nokaslr" -drive if=pflash,file=rootfs.ext2,format=raw` * `qemu-system-ppc -M ppce500 -cpu e500mc -m 256 -kernel uImage -append "console=ttyS0 rootwait root=/dev/mmcblk0" -device sd-card,drive=mydrive -drive id=mydrive,if=none,file=rootfs.ext2,format=raw` The load was created using latest Buildroot with `make qemu_ppc_e500mc_defconfig` where the rootfs was configured to be of ext2 type. In both cases it was possible to log in and explore the root file system. v2: ~~~ Bin: - Add source for MPC8544DS platform bus' memory map in commit message. - Keep "ESDHC" in comment referring to Linux driver. - Use "qemu-system-ppc{64|32} in documentation. - Use g_autofree in device tree code. - Remove unneeded device tree properties. - Error out if pflash size doesn't fit into eLBC memory window. - Remove unused ESDHC defines. - Define macro ESDHC_WML for register offset with magic constant. - Fix some whitespace issues when adding eSDHC device to e500. Phil: - Fix tense in commit message.
