The new command:
ethsw [port <port_no>] [vlan <vid>] fdb
{ [help] | show | flush | { add | del } <mac> }
Can be used to add and delete FDB entries. Also, the command can be used
to show entries from the FDB tables. When used with [port <port_no>]
and [vlan <vid>], only the matching the FDB entries can be seen or
flushed. The command has also been added to the generic ethsw parser
from cmd_ethsw.c.

The code that checks if a string has the format of a MAC address has been
moved to a separate function called eth_validate_ethaddr_str().
This has been done to allow other components (such as vsc9953 driver)

This patch creates a flexible parser for Ethernet Switch
configurations that should support complex commands.
The parser searches for predefined keywords in the command
and calls the proper function when a match is found.
Also, the parser allows for optional keywords, such as
"port", to apply the command on a port
or on all ports. For now, the defined commands are:
ethsw [port <port_no>] { enable | disable | show }

At startup, the default configuration should be:
- enable HW learning on all ports (HW default);
- all ports are VLAN aware;
- all ports are members of VLAN 1;
- all ports have Port-based VLAN 1;
- on all ports, the switch is allowed to remove
maximum one VLAN tag,
- on egress, the switch should add a VLAN tag if the
frame is classified to a different VLAN than the port's
Port-based VLAN;

When a port is enabled at init time, the initializing function
touches more bits than necessary to enable a port (also touches
reserved bits and default bit values). This patch fixes this issue
by changing the value of the define used to enable the port and
assures that no other bits are changes by replacing out_le32()
with setbits_le32().

Quark SoC does not support MSR MTRRs. Fixed and variable range MTRRs
are accessed indirectly via the message port and not the traditional
MSR mechanism. Only UC, WT and WB cache types are supported.
We configure all the fixed range MTRRs with common values (VGA RAM
as UC, others as WB) and 3 variable range MTRRs for ROM/eSRAM/RAM as
WB, which significantly improves the boot time performance.
With this commit, it takes only 2 seconds for U-Boot to boot to shell
on Intel Galileo board. Previously it took about 6 seconds.

On currently supported SoCs, clk_m always runs at the same frequency as

AFAIK, for all PLLs on all Tegra SoCs, the primary PLL output frequency
is (input * m) / (n * p). However, PLLP's primary output (pllP_out0) on
T210 is the VCO output, and divp is not applied. pllP_out2 does have divp
applied. All other pllP_outN are divided down from pllP_out0. We only
support pllP_out0 in U-Boot at the time of writing.
Fix clock_get_rate() to handle this special case.
This corrects the returned rate for PLLP to be 408MHz rather than 204MHz.
In turn, this causes high enough dividers to be calculated for the various
peripheral clocks that feed off of PLLP. Without this, some peripherals
failed to operate correctly. For instance, one of my SD cards worked
perfectly but an older (presumably slower) card could not be read.
Note that prior to commit 722e000ccd72 "Tegra: PLL: use per-SoC pllinfo
table instead of PLL_DIVM/N/P, etc.", the calculated PLL frequency was
816MHz since the wrong values were being extracted from the PLLP divider
register. This caused overly large peripheral dividers to be calculated,
which while wrong, didn't cause any correctness issues; things simply ran
slower than they could.

While T210 boards all have 38.4MHz crystals, per the TRM, the only
supported configuration is to divide the crystal frequency by 2 to
generate clk_m, which is what feeds the ARM generic timers amongst other
things. Fix the value of COUNTER_FREQUENCY to reflect this divide-by-2.
When I queried the 19.2 value in Tom's original T210 patches, I wasn't
aware of this extra divide-by-2, and didn't notice any effect from the
incorrect value, since its only used if U-Boot is booted in EL3, whereas
I'm booting it in EL2.

When enabling CONFIG_API and chain-loading GRUB2 on jetson-tk1, only the
eMMC would show up as (hd0), but not the SD card, leading to GRUB not
finding its configuration and modules, falling back to a rescue shell.
This is because enum_ended would get set for !more after returning a
cookie for the first MMC device in group 3.
Fix this by properly setting the "more" argument also in the case of the

- CONFIG_PL011_SERIAL_FLUSH_ON_INIT
As they only seem to be referenced by u8500 based boards. Without any

from file
Lets consider following scenario:
- One uses echo -n "key=value" to define environment variable in a file (single variable)
- The file content is "key=value" without any terminating byte (e.g. 0x0a or
0x0d).
- The file is loaded to u-boot non zero'ed RAM buffer (with load command).
- Then "env import -t -r $loadaddr $filesize" is executed.
- Due to lack of proper termination byte we have classical example of buffer
overrun.
This patch prevents from this by allocating one extra byte than size and
explicitly null terminate it.
There should be no change for normal env import operation after applying
this patch.
