The i.MX6 uses the same GPMI NAND controller as i.MX23/28 do. This adds
i.MX6 support to the driver.

Use MMC_CAP_ names instead of MMC_MODE_. This makes it more
clear that these are capabilities of host/card and do not refer
to the current mode. These are in line with the Linux Kernel
except for MMC_CAP_MMC_HIGHSPEED_52MHZ which could be fixed
later.

This is a port of the official PLL errata workaround from Freescale.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.
This is based on U-Boot commit:

clock_notifier_call_chain() can't be called before init time. Protecting
it with IS_ENABLED(__PBL__) is not enough. This patch splits out a new
imx53_init_lowlevel_early which can be called before init time and does
not have the call to clock_notifier_call_chain() in it.

The value for i.MX53 216MHz is actually 432MHz. Use the same value
as for i.MX51 which really corresponds to 216MHz. These are the same
PLL216 values as U-Boot uses.

This patch seperates the imx independent from the arch independent code. The

The external NAND boot code currently does not handle bad blocks
correctly on 2k NAND flashes. This patch adds a barebox_update
handler for external NAND boot which embeds a Bad block table in
the flashed image. The boot code will skip bad blocks found in
this bad block table then.

Instead of using STACK_BASE use a stack in internal SRAM to get rid

The pattern for i.MX boards starting in external NAND boot mode is always
the same:
- Check if we are running in NFC address space, if not call
board_init_lowlevel_return()
- copy binary to link address
- execute relocated binary
- call imx_nand_load_image()
Add a common function for this to make the board code easier.
