Follow up to commit 8fb714edd6. Managed to
hit the very same issue again while playing with the NOR SPL builds.

At least since gcc 7.3.0 (OpenWrt 18.06) lwr/lwl are used in the
assembly of LzmaProps_Decode. While the decission made by the compiler
looks perfect fine, it triggers some obscure hang on lantiq danube-s
v1.5 with MX29LV640EB NOR flash chips.
Only if the offset 1 is used, the hang can be observed. Using any other
offset works fine:
lwl s0,0(a1) - s0 == 0x6d000080
lwl s0,1(a1) - hangs
lwl s0,2(a1) - s0 == 0x0080xxxx
lwl s0,3(a1) - s0 == 0x80xxxxxx
It isn't clear whether it is a limitation of the flash chip, the EBU or
something else.
Force 8bit reads to prevent gcc optimizing the read with lwr/lwl
instructions.

In dtc version 1.4.6 the macro names in header include guards changed,
but the build relies on them matching in order to replace selected
headers. This is a horrible hack to work around this.

Backing up the current firmware from U-Boot over serial can take hours.
Booting a working Linux image for backup purposes is not always an option.
Using the tftpput command in U-Boot is the fastest and easiest way.
tftpput will upload the contents of a memory region to the TFTP server.
The IP address of the server is stored in the serverip variable.
Usage:
tftpput <memaddr> <length> <filename>
Example for a complete flash backup of an o2 Box 6431 (VGV7510KW22):
VGV7510KW22 # tftpput 0xB0000000 0x1000000 o2boxbackup.bin

Increasing CONFIG_SYS_BOOTM_LEN from 8 MB to 16 MB is necessary to
support uncompressing images larger than 8 MB when using the bootm
command.

Based on the submission to the uboot-lantiq repo by Martin Blumenstingl.
Use the ddr_settings.h from the GPL tarball. The NAND boot optimized
one (with memory tuning enabled) doesn't work for the UART boot image.
Use the same mtd layout as the stock u-boot. Add add UBI support.
Use the leds to indicate boot status like it is done with the stock
u-boot. Switch on the red power led if kernel image can't be loaded.
Otherwise switch the green led on.
Make only the ramboot u-boot available. Only this image is required for
the first installation of LEDE.

Based on a submission to the uboot-lantiq repo by Eddi De Pieri.
Major cleanup and addition of brnboot second stage u-boot was done by
me.
The second stage brnboot u-boot is untested, since the brnboot prompt
is secured by a still unknown password. But should work.
The former ram values are replaced with the ram values extracted from
the original brnboot. The old ones didn't worked with the ramboot
image.

The default bootloader partition of some devices is to small for an
u-boot with uncompressed gphy firmware(s).
Instead of increasing the bootloader partition size, in compare to the
stock firmware, compress the firmware. This would allow the bootloader
of at least the FritzBox 3370 as well as the bootloader of the
VGV7510KW22 to fit into the bootloader partition of the stock firmware.

Devices like the xrx200 Arcadyan VGV7519 are using two NOR flash chips.

According to the author, all SPI related configs are copy & paste
leftovers. Which makes sense since nothing is connected to the SPI bus
on this device.
The NOR SPL isn't required for this board, since the NOR is directly
memory mapped.
Allow to overwrite the env in ram while using brn variant. Do not set
the power GPIO pin twice.

use:
- 00nn for u-boot patches
- 01nn for new boards
While doing the rework, the board definitions for the easy50712 and
easy80920 were moved to distinct board definitions patches.
