Fixes: 65071bd arm: Clarify memory layout calculation
arm_mem_barebox_image() shall return the beginning of the barebox
image (and thus the end of the malloc region). For relocatable
images we can return a suitable location, but for non relocatable
images we do not have a choice: We must return TEXT_BASE. If TEXT_BASE
happens to be outside the memory region between membase and endmem
we can return the base of the ramoops area.

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.

The HABv3 images for engineering mode do not work on a production device
and the images for production mode do not work on an engineering device.
When in engineering mode the ROM checks the images, but does not stop
booting when the signatures are wrong. This means a production image
can still be booted on an engineering device. This device can be
temporarily put into production mode by writing to the HAB_TYPE shadow
fuse register. After a reset the device will come up in production mode
and the image can be tested for validity. This means that if we have to
decide between production mode images and engineering images, the
production images are a better decision. Change this accordingly.

This adds a function to enable/disable permanent write for the IIM
module so that C users no longer have to fiddle with device parameters.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Accessing the IIM registers is cumbersome. The fuses are documented with
different register strides and there is no header file available, so the
different fields have to be read in the datasheets and translated into
the barebox format over and over again. This patch adds a header file
which has defines for the various fuses (for i.MX25 only so far, but
others can be added later) along with C functions to read/write the
fields.

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

The phyCORE-i.MX6 has either a NAND or EMMC storage device and an
external SD-Card interface. The automatic bootsource detection in the
barebox environment should reflect that.
- If the board was booted from the external SD-Card interface, it should
continue loading the kernel and device tree from it.
- If the board was booted from EMMC, it should load kernel and device
tree from the boot partition on the EMMC.
