Since patch e92abad363 the linker discards sections which seems not
used to make the image smaller.
But this change will discard the whole init and exception code from start.S
which renders the final image useless.
From 'barebox.map' without this patch:
Discarded input sections
.text 0x0000000000000000 0x358c arch/ppc/mach-mpc5xxx/start.o
.data 0x0000000000000000 0x0 arch/ppc/mach-mpc5xxx/start.o

.got2 0x0000000000000000 0x24 arch/ppc/mach-mpc5xxx/start.o
[...]
So, define the entry point to mark the init and exception used.

Author: Sascha Hauer <s.hauer@pengutronix.de>

imd: use struct imd_header * as argument
introduces additional imd type checks like this
if (!imd_is_string(imd->type))
return NULL;
These checks work incorrectly on any big-endian machine
because the imd->type field needs addition conversion
to little-endian byteorder before use.
Here is the imd command output on big-endian qemu-malta:
barebox:/ imd /dev/nor0.barebox
release: <NULL>
build: <NULL>
This patch fixes the problem by adding necessary conversion
via imd_read_type().

First of all the reset values of MMC interfaces are differently between
Quad and DualLite/Solo SoM.
Register VEND_SPEC2(0xC8)
Quad: 0x0
DualLite: 0x00000006
default: 0x00000006 (from i.MX6 Reference Manual)
Furthermore the ROM Code of Quad and DualLite uses the MMC interfaces
differently when it loads the bootloader from that device:
Register DLL_CTRL(0x60) Bit 25 FBCLK_SEL (0x48)
Quad: 0x0 0
DualLite: 0x01000021 1
Since the linux kernel and barebox driver doesn't reset all registers,
the MMC interface is in an inconsistent state, which leads to boot
failures for some eMMC devices on the i.MX6 DualLite SoM. The errors
look like:
mmcblk3: error -110 sending stop command, original cmd response 0x900, card status 0x400900
mmcblk3: error -84 transferring data, sector 24578, nr 2, cmd response 0x900, card status 0x0
mmcblk3: retrying using single block read
mmcblk3: error -84 transferring data, sector 24578, nr 2, cmd response 0x900, card status 0x0
blk_update_request: I/O error, dev mmcblk3, sector 24578
It's sufficient to reset register DLL_CTRL and bit FBCLK_SEL. Register
VEND_SPEC2 has no effect.

It becomes a common case that the Kernel is loaded from the filesystem
which later becomes the rootfs. This adds a possibility to let bootm

is done when global.bootm.appendroot is true.

The settings in GPR8 are dependent upon the particular layout of the
hardware platform. As such, they should be configurable via the device
tree.
Look up PHY Tx driver settings from the device tree. Fall back to the
original hard-coded values if they are not specified in the device tree.
