The previous code wrote the contents of the fuse as is in the
REFTOP_VBGADJ[2:0], but this was wrong if you consider the contents of
the table in the code comment. This table is also different from the
table in the commit description. But then, which of the two is correct?
If it is assumed that an unprogrammed fuse has a value of 0 then for
backward compatibility of the code REFTOP_VBGADJ[2:0] must be set to
6 (b'110). Therefore, the table in the code comment can be considered
correct as well as this patch.

According to TRM for i.MX8M Nano and Plus, GPR10 register contains lock
bit for TZASC_ID_SWAP_BYPASS bit. This bit is required to be set in
order to avoid AXI bus errors when GPU is enabled on the platform.
TZASC_ID_SWAP_BYPASS bit is alread set for all imx8m applicable
derivatives, but is missing a lock settings to be applied.
Set the TZASC_ID_SWAP_BYPASS_LOCK bit for those derivatives which have

Since we're here, provide also names to bits from TRM instead of using
BIT() macro in the code.

Add support of secondary boot address for imx8mn. The secondary
boot address is hardcoded in the fuse. The value is calculated
from there according to the following description:
The fuse IMG_CNTN_SET1_OFFSET (0x490[22:19]) is defined as follows:
- Secondary boot is disabled if fuse value is bigger than 10, n = fuse
value bigger than 10.
- n == 0: Offset = 4MB
- n == 2: Offset = 1MB
- Others & n <= 10 : Offset = 1MB*2^n
- For FlexSPI boot, the valid values are: 0, 1, 2, 3, 4, 5, 6, and 7.

Similar to what has been done before with c5437e5b for u-boot proper, we
enable the SMP bit for SPL as well. This is necessary when SDP booting
straight into Linux, i.e. falcon boot. When SDP boot mode is active, the
ROM code does not set this bit which makes the caches not work once
activated in Linux.
On an i.MX6ULL (528MHz), this reduces a minimal kernel's boot time into
an initramfs shell from ~6.1s down to ~1.2s.

With the current configuration provided in mxsimage{-spl}.mx28.cfg the
size of SPL binary has been constrained to 32 KiB, due to "LOAD IVT"
command with 0x8000 offset.
The problem was that, the imx28 ROM takes the u-boot.sb and then
extracts from it the IVT header and places it on the 0x8000 OCRAM offset
overwriting any valid (i.e. loaded from eMMC or SPI-NOR) SPL code. This
bug was unnoticed as the overwrite size was just 32 bytes, so the
probability that some important code is altered was low.
However, in the XEA board (where the SPL size is ~39KiB), the overwritten
data was `(struct dm_spi_ops *) 0x800c <mxs_spi_ops>`, which is used
during the boot process.
As a result the SPL execution code hanged with "undefined instruction"
abort as callbacks (with wrong addresses) from it were called.
The fix is to change the OCRAM's offset where IVT is loaded to 0xE000,
so the SPL can grow up to ~57KiB (the maximal size of OCRAM memory
available is 0xE3FC).

According to the i.MX6ULL Reference Manual, pad CSI_DATA07 may
have the ESAI_TX0 functionality, not ESAI_T0.
Also, NXP's i.MX Config Tools 10.0 generates dtsi with the
MX6ULL_PAD_CSI_DATA07__ESAI_TX0 naming, so fix it accordingly.
There are no devicetree users in mainline that use the old name,
so just remove the old entry.

The PDK2 board is capable of running both 100M and 1G ethernet. However,
the i.MX6 has only one ethernet MAC, so it is possible to configure
either 100M or 1G Ethernet. In case of 100M option, the PHY is on the
SoM and the signals are routed to a RJ45 port. For 1G the PHY is on
the PDK2 board with another RJ45 port. 100M and 1G ethernet use
different signal pins from the i.MX6, but share the MDIO bus.
This SoM board combination is used to demonstrate how to enable 1G
ethernet configuration.
