dcb59a1306 ARM: dts: imx: Simplify fec node for iMX6QDL DHCOM boards
Firstly the FEC can now use the regulator reg_eth_vio from
imx6qdl-dhcom-som.dtsi instead of defining its own.

Secondly the &fec node is moved to the more generic SoM device tree
file, because it can be used by multiple boards.

6ecd1d66a9 ARM: imx6: Remove CONFIG_FEC_MXC_PHYADDR from DH header
Use phy address from device tree instead of CONFIG_FEC_MXC_PHYADDR from
board header. This is required, because the DH picoITX and DRC02 boards
require different settings than PDK2. The corresponding 'phy-handle'
device tree properties are already there.

I tested this change on picoITX and DRC02, but on PDK2 it is untested.

a222c14792 mtd: nand: mxs_nand_spl: Fix bad block skipping
The specific implementation was having bug. Those bugs are since
the beginning of the implementation. Some manufactures can already
experience this bug in their SPL code. This bug can be more visible on
architecture that has complicated boot process like imx8mn. Older
version of uboot can be affected if the bad block
appear in correspoding of the beginning of u-boot image. In order to
adjust the function we scan from the first erase block.

The problematic part of old code was in this part:

while (is_badblock(mtd, offs, 1)) {
           page = page + nand_page_per_block;
          /* Check i we've reached the end of flash. */
          if (page >= mtd->size >> chip->page_shift) {
                      free(page_buf);
                      return -ENOMEM;
         }
}

Even we fix it adding increment of the offset of one erase block size
, we don't fix the problem, because the first erase block where the
image start is not checked. The code was tested on an imx8mn where
the boot rom api was not able to skip it. This code is used by other
architecures like imx6 and imx8mm

290ffe5788 imx8m: fix reading of DDR4 MR registers
I was trying to employ lpddr4_mr_read() to something similar to what
the imx8mm-cl-iot-gate board is doing for auto-detecting the RAM
type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c
differs from the private one used by that board in how it extracts the
byte value, and I was only getting zeroes. Adding a bit of debug
printf'ing gives me

 tmp = 0x00ffff00
 tmp = 0x00070700
 tmp = 0x00000000
 tmp = 0x00101000

and indeed I was expecting a (combined) value of 0xff070010 (0xff
being Manufacturer ID for Micron). I can't find any documentation that
says how the values are supposed to be read, but clearly the iot-gate
definition is the right one, both for its use case as well as my
imx8mp-based board.

So lift the private definition of lpddr4_mr_read() from the
imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration
in the ddr.h header where e.g. get_trained_CDD() is already declared.

This has only been compile-tested for the imx8mm-cl-iot-gate
board (since I don't have the hardware), but since I've merely moved
its definition of lpddr4_mr_read(), I'd be surprised if it changed
anything for that board.

c329f9349b ARM: imx: imx31: Introduce and use UART_BASE_ADDR(n)
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base
address. Convert all board configurations to this new macro. This is the
first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a
clean up, no functional change.

The new macro contains compile-time test to verify N is in suitable
range. The test works such that it multiplies constant N by constant
double-negation of size of a non-empty structure, i.e. it multiplies
constant N by constant 1 in each successful compilation case.

The non-empty structure may contain C11 _Static_assert(), make use of
this and place the kernel variant of static assert in there, so that
it performs the compile-time check for N in the correct range. Note
that it is not possible to directly use static_assert in compound
statements, hence this convoluted construct.
