4835d35acf charset: Add support for calculating bytes occupied by a u16 string
The current code uses 'u16_strlen(x) + 1) * sizeof(u16)' in various
places to calculate the number of bytes occupied by a u16 string.
Let's introduce a wrapper around this. This wrapper is used on following

e519f03a18 cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mapping
There is no real need to exactly define space for saving patterns for
alternate memory test. It is much easier to allocate space on the stack and
use it instead of trying to find out space where pattern should be saved.

For example if you want to test the whole DDR memory you can't save patter
to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses
were chosen but that means that OCM needs to be mapped and U-Boot has
access permission there.

It is easier to remove this limitation and simply save it on stack because
it is very clear that memory test can't rewrite U-Boot and U-Boot has also
full access to memory where runs from.

fe6293a809 phy: atheros: add device tree bindings and config
Add support for configuring the CLK_25M pin as well as the RGMII I/O
voltage by the device tree.

By default the AT803x PHYs outputs the 25MHz clock of the XTAL input.
But this output can also be changed by software to other frequencies.
This commit introduces a generic way to configure this output.

Also the PHY supports different RGMII I/O voltages: 1.5V, 1.8V and 2.5V.
An internal LDO is able to provide 1.5V (default) and 1.8V. The 2.5V
option needs an external supply voltage. This commit adds support to
switch the internal LDO to 1.8V.

5168d7a626 menu: add support for client defined statusline function
Currently displaying status line is done in a weak function
menu_display_statusline().

bootmenu.c overrides the weak default function.
It calls menu_default_choice() and interprets the data as
struct bootmenu_entry.

pxe boot also uses common menu code for pxe menus.
If there is a system that enables both bootmenu and pxe,
menu_display_statusline() defined in bootmenu.c will be called
and it will interpret struct pxe_label as struct bootmenu_entry.
This leads to data aborts and pxe menu corruptions.

This patch adds support for client defined statusline function
to resolve the above bug.

56e403d95f arm: juno: enable USB
The Juno board features a standard compliant EHCI/OHCI USB host
controller pair, which we can just enable.
The platform data is taken from the device tree.

This allows to use USB mass storage (the only storage on a Juno r0)
for loading.

At least on my board USB seems a bit flaky, I need two "usb reset"
sequences after the "usb start" to detect an USB hard drive.

7d6dae0dfb arm: juno: Fix Juno address variables
The U-Boot documentation explains that variables ending with "_r" hold
addresses in DRAM, while those without that ending point to flash/ROM.
The default variables for the Juno board pointing to the kernel and DTB
load addresses were not complying with this scheme: they lack the
extension, but point to DRAM. This is particularly confusing since the
Juno board features parallel NOR flash, so there *is* a memory mapped
NOR address holding a DTB, for instance.

Fix the variables to use the proper names, changing initrd_addr to
ramdisk_addr_r on the way, which seems to be more prevelant and
documented. On the way adjust the FDT load address to be situated
*before* the kernel, since users happened to overwrite the DTB by the
kernel clearing its .BSS section during initialisation.
Also remove the fdt_high and initrd_high variables (which were set
to -1), to allow U-Boot moving those images around.

This should avoid many problems in the future, but breaks loading
Linux kernels < v4.2, since they expect the DTB to be loaded in the same
512MB region as the kernel. If you need to load such an old kernel,
please set fdt_high to either 0xffffffffffffffff or 0xa0000000 (if you
load the kernel to the beginning of DRAM).

That fixes loading debug kernels, which happened to overwrite the DTB on
certain setups.

682fef9ff6 include/eeprom.h: fix build errors
CMD_EEPROM and ENV_IS_IN_EEPROM can be selected independently, and
cmd/eeprom.o gets built in either case, so whether to declare the real
prototypes needs to follow the same logic as whether cmd/eeprom.c is
built. Otherwise a ENV_IS_IN_EEPROM=y, CMD_EEPROM=n build fails

cmd/eeprom.c:73:1: error: expected identifier or ‘(’ before ‘{’ token

While at it, fix the dummy replacements (at least assuming they are
meant to allow the code to compile) - they need to have the same type
as the expression they replace, or one gets errors such as

env/eeprom.c: In function ‘eeprom_bus_read’:
env/eeprom.c:37:8: error: void value not ignored as it ought to be

164fed941f treewide: Remove unused FSL QSPI config options for IMX platforms
Some of these options are not used by the driver anymore and some of them
are obsolete as the information is gathered from the dt.
So, remove the unused config options now.

5e0ceb0bbd config: apalis-imx8: Enable FEC TXC delay
define FEC_ENET_ENABLE_TXC_DELAY to enable the delay on TXC line on
the MAC. This has to be done in order to meet RGMII specs.
According to RGMII specs the clock should get delayed so the edges of
the clock are preferrably in the middle of the edges of data-lines so
they can be sampled properly.
Our PHY expects the MAC to delay TXC line, as it is also written
in the spec. This patch makes sure the TXC delay on the FEC is enabled

f72e48ba4d board: apalis_imx6: Add KSZ9131 phy skew settings
This patch adds skew register settings for KSZ9131. It checks first
which phy is on the board and then applies the correct skew settings.

Skew settings calculation for the KSZ9131:
The i.MX6 SoC has an output skew tolerance of -100ps to 900ps. All
PCB traces where routed exactly the same length so we can calculate
the skew settings without taking the length into consideration. The
traces are all length matched.

RXC skew (PHY to MAC):
- We use the 2ns DLL controlled delay on the PHY
- We do not use the skew registers

This results in the following values:

		RXC
PHY fixed Delay	2000ps
PHY Added Delay	0ps
T_setup_R min	2.00ns
T_setup_R typ	2.00ns
T_setup_R max	2.00ns
T_hold_R min	1.60ns
T_hold_R typ	2.00ns
T_hold_R max	2.40ns

That means we are well within RGMII specs.

TXC skew (MAC to PHY):
- We use the 2ns DLL controlled delay on the PHY
- We then subtract ~0.6ns with TXD[0:3] and TXC clock pad skew
  register in a resulting ~1.4ns delay.

This results in the following values under consideration of the
tolerances:

		TXC min	TXC typ	TXC max
MAC min		-100ps	-100ps	-100ps
MAC max		900ps	900ps	900ps
PHY fixed Delay	2000ps	2000ps	2000ps
PHY added Delay	-340ps	-600ps	-859ps
T_setup_T min	1.56ns	1.30ns	1.04ns
T_setup_T typ	2.06ns	1.80ns	1.54ns
T_setup_T max	2.56ns	2.30ns	2.04ns
T_hold_T min	1.04ns	1.30ns	1.56ns
T_hold_T typ	1.94ns	2.20ns	2.46ns
T_hold_T max	2.84ns	3.10ns	3.36ns

This shows that T_hold_T min and T_setup_T min times are out of spec
for RGMII timing. However the KSZ9131 has a minimal value for this time
of 0.8ns which is met under all circumstances.
