armv8: Add tlb_allocated to arch global data
When secure ram is used, MMU tables have to be put into secure ram.
To use common MMU code, gd->arch.tlb_addr will be used to host TLB
entry pointer. To save allocated memory for later use, tlb_allocated
variable is added to global data structure.
Add support for Advantech SOM-DB5800 with the SOM-6867 installed.
This is very similar to conga-qeval20-qa3-e3845 in that there is a
reference carrier board (SOM-DB5800) with a Baytrail based SoM (SOM-6867)
installed.
Currently supported:
- 2x UART (From ITE EC on SOM-6867) routed to COM3/4 connectors on
SOM-DB5800.
- 4x USB 2.0 (EHCI)
- Video
- SATA
- Ethernet
- PCIe
- Realtek ALC892 HD Audio
Pad configuration for HDA_RSTB, HDA_SYNC, HDA_CLK, HDA_SDO
HDA_SDI0 is set in DT to enable HD Audio codec.
Pin defaults for codec pin complexs are not changed.
Not supported:
- Winbond Super I/O (Must be disabled with jumpers on SOM-DB8500)
- USB 3.0 (XHCI)
- TPM

test/py: strip VT100 codes from match buffer
Prior to this patch, any VT100 codes emitted by U-Boot are considered part
of a command's output, which often causes tests to fail. For example,
test_env_echo_exists executes printenv, and then considers any text on a
line before an = sign as a valid U-Boot environment variable name. This
includes any VT100 codes emitted. When the test later attempts to use that
variable, the name would be invalid since it includes the VT100 codes.
Solve this by stripping VT100 codes from the match buffer, so they are
never seen by higher level test code.
The codes are still logged unmodified, so that users can expect U-Boot's
exact output without interference. This does clutter the log file a bit.
However, it allows users to see exactly what U-Boot emitted rather than a
modified version, which hopefully is better for debugging. It's also much
simpler to implement, since logging happens as soon as text is received,
and so stripping the VT100 codes from the log would require handling
reception and stripping of partial VT100 codes.

pci: tegra: correctly program PADS_REFCLK registers
The value that should be programmed into the PADS_REFCLK register varies
per SoC. Fix the Tegra PCIe driver to program the correct values. Future
SoCs will require different values in cfg0/1, so the two values are stored
separately in the per-SoC data structures.
For reference, the values are all documented in NV bug 1771116 comment 20.
The Tegra210 value doesn't match the current TRM, but I've filed a bug to
get the TRM fixed. Earlier TRMs don't document the value this register
should contain, but the ASIC team has validated all these values, except
for the Tegra20 value which is simply left unchanged in this patch.
