66f119e50c net/designware: Consecutive writes to the same register to be avoided
This commit is an add-on to f6c4191f. There are a few registers where
consecutive writes to the same location should be avoided or have a delay.

According to Synopsys, here is a list of the registers and bit(s) where
consecutive writes should be avoided or a delay is required:

DMA Registers:
Register 0        Bit 7
Register 6        All bits except for 24, 16-13, 2-1.

GMAC Registers:
Registers 0-3     All bits
Registers 6-7     All bits
Register 10       All bits
Register 11       All bits except for 5-6.
Registers 16-47   All bits
Register 48       All bits except for 18-16, 14.
Register 448      Bit 4.
Register 459      Bits 0-3.

bc46dfac2f net: tftp: fix type of block arg to store_block
The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.

In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.

A known hardware issue of USB1 port where bit 1 (connect status
change) of PORTSC register will be set after issuing Port Reset
(like "usb reset" in u-boot command line).
This will be treated as an error and stops later device enumeration.

Therefore we clear that bit after Port Reset in order to proceed

2db7b95284 tegra: trimslice: set up serial flash pinmux
When Trimslice is booted from serial flash, the boot ROM does this, so
U-Boot doesn't need to. However, booting from the SD slot for recovery
purposes, the boot ROM does not set up the pinmux for serial flash. Add
code to U-Boot to set this up, so that an SD-based recovery U-Boot image
can upgrade the U-Boot in serial flash.

03cddf28eb tegra: bootcmd enhancements
Place the list of searched boot devices, file-system types, boot file
locations/prefixes, and boot script names into variables. This allows
the user to override them directly (e.g. to change boot order, or select
the specific values they use) without having to edit the main bootcmd
and script_boot variables.

The default boot order is changed from USB, MMC, DHCP to MMC, USB, DHCP.
This speeds up the typical MMC boot case. People who want USB boot can
now edit variable boot_targets appropriately.

Also, reformat BOOTCMDS_COMMON to fit within 80 columns.

Potential future enhancements might be:
* Allow boards to specify which of bootcmd_mmc0/... should be defined,
  based on the HW they contain.
* Allow boards to influence the order that the boot targets are added
  into the boot_targets variable.

9cd3f3adf0 tegra: add enterrcm command
Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.

This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

Power sequencing hardware on the carrier pulls the reset low before

58e22f8a15 fdt: send all dtc output to stderr
Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture
the result code from dtc by echoing $? to stdout and capturing it using
$(). However, dtc emits some diagnostics to stderr and some to stdout.
The diagnostics send to stdout ended up getting captured via $() rather
than being echo'd to the user. This caused those diagnostics to be passed
to the exit command, which would then fail with the following cryptic
error message:

    /bin/sh: line 1: exit: too many arguments

Solve this by redirecting all dtc output to stderr so that $() does not
capture it. This allows the user to see the actual error message from dtc.

SRICHARAN R
d702b0811d ARM: cache: Move the cp15 CR register read before flushing the cache.
The following is the cleanup sequence in arch/arm/cpu/armv7/cpu.c

int cleanup_before_linux(void)
{
 ...
 ...
 dcache_disable();
 v7_outer_cache_disable();
 invalidate_dcache_all();
}

 1) invalidate_dcache_all call expects that all the caches has been
 flushed, invalidated and there are no dirty entries prior to its
 execution.  In the above sequence dcache_disable() flushes, invalidates
 the caches and turns off the  mmu. But after it cleanups the cache
 and before the mmu is disabled  there is a cp_delay() function which
 has STR instruction. On certain cores like the cortex-a15, cache hit
 and a write can happen to a cache line even when the dcache is
 disabled. So the above mentioned STR instruction creates a dirty entry
 after cleaning. The mmu gets disabled after this.

 2) invalidate_dcache_all invalidates the cache lines. Again on
 cores like cortex-a15, invalidate instruction flushes the dirty
 line as well. So some times the dirty line from sequence 1
 can corrupt the memory resulting in a crash.

 Fixing this by moving the get_cr() and cp_delay() calls before
 cleaning up the cache, thus avoiding the dirty entry.
