powerpc/boot: Change the macro of Boot from SRIO and PCIE master module
Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable
the master module of Boot from SRIO and PCIE on a platform. But this
is not a silicon feature, it's just a specific booting mode based on
the SRIO and PCIE interfaces. So it's inappropriate to put the macro
into the file arch/powerpc/include/asm/config_mpc85xx.h.
Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to
"CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from
arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros
in configuration header file of each board which can support the
master module of Boot from SRIO and PCIE.

fsl_esdhc: Do not clear interrupt status bits until data processed
After waiting for the command completion event, the interrupt status
bits, that occured to be set by that time, are cleared by writing them
back. It is supposed, that it should be command related bits (command
complete and may be command errors).
However, in some cases the DMA already completes by that time before
the full transaction completes. The corresponding DINT bit gets set
and then cleared before even entering the loop, waiting for data part
completion. That waiting loop never gets this bit set, causing the
operation to hang. This is reported to happen, for example, for write
operation of 1 sector to upper area (block #7400000) of SanDisk Ultra II
8GB card.
The solution could be to explicitly clear only command related interrupt
status bits. However, since subsequent processing does not rely on
any command bits state, it could be easier just to remove clearing
of any bits at that point, leaving them all until all data processing
completes. After that the whole register will be cleared at once.
Also, on occasion, interrupts masking moved to before writing the command,
just for the case there should be no chance of interrupt between the first
command and interrupts masking.

mmc write bug fix
This patch fixes a bug related to mmc writes.
When doing fatwrites on an SD-Card, MMC bus problems can occur. Depending
on the size of the file, "MMC0: Bus busy timeout!" is reported, resulting
in an SD-Card that is no longer responding.
It appears to be, that set_cluster can be called with a size being zero.
That can be with a file that has a size being an exact multiple
(including 0) of the clustersize, but also for files that are smaller than
the size of one cluster.
The same problem occurs if the "mmc write" command is given with a block
count being 0.
By adding a check for the block count being zero in mmc_write_blocks
(drivers/mmc.c), this problem is solved.

usb: ehci: add Faraday USB 2.0 EHCI support
This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:
1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
compatible with the general TDI implementation
found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
several ways. But since U-boot doesn't support ISOC,
we don't have to worry about that.

usb: ehci: prevent bad PORTSC register access
1. The 'index' of ehci_submit_root() is not always > 0.
e.g.
While it gets invoked from usb_get_descriptor(),
the 'index' is always a '0'. (See ch.9 of USB2.0)
2. The PORTSC register is not always required, and thus it
should only report a port error when necessary.
It would cause a port scan failure if the ehci_submit_root()
always gets terminated by a port error.

usb: asix: Move software resets to basic_init
The ASIX driver calls a basic_init() function during get_info(), so that
not all initialization tasks need to be redone on every init().
Unfortunately, the most important one is still triggered too often: the
driver does a full port and MII reset on every asix_init(), requiring up
to several seconds to reestablish the link.
This patch confines that software reset into the asix_basic_init()
function so that it will only be executed once. This saves about a
second of boot time on systems using BOOTP.
Note: this patch was previously submitted many moons ago as:
usb: usbeth: asix: Do a fast init if link already established
That patch seens to have been lost or forgotten, so this is a rebased
version. It is tested on snow with a Asix USB dongle (Cisco).

ppc: ppmc7xx: Fix possible out-of-bound access
The flash_info_t->start[] field is limited in size by CONFIG_SYS_MAX_FLASH_SECT
macro, which is set to 19 for this board in the board config file. If we inspect
the board/ppmc7xx/flash.c closely, especially the flash_get_size() function, we
can notice the "switch ((long)flashtest)" at around line 80 having a few results
which will set flash_info_t->sector_count to value higher than 19, for example
"case AMD_ID_LV640U" will set it to 128. Notice that right underneath, iteration
over flash_info_t->start[] happens and the upper bound for the interation is
flash_info_t->sector_count. Now if the sector_count is 128 as it is for the
AMD_ID_LV640U case, but the CONFIG_SYS_MAX_FLASH_SECT limiting the start[] is
only 19, an access past the start[] array much happen. Moreover, during this
iteration, the field is written to, so memory corruption is inevitable.

fdt: remove unaligned access in fdt_fixup_ethernet()
Some ARM compilers may emit code that makes unaligned accesses when
faced with constructs such as:
char mac[16] = "ethaddr";
Replace this with a strcpy() call instead to avoid this. strcpy() is
used here, rather than replacing all usage of the mac variable with the
string itself, since the loop itself sprintf()s to the variable each
iteration, so strcpy() is doing basically the same thing.

generic_board: reduce the redundancy of gd_t struct members
This commit refactors common/board_f.c and common/board_r.c
in order to delete the dest_addr and dest_addr_sp from
gd_t struct.
As mentioned as follows in include/asm-generic/global_data.h,
/* TODO: is this the same as relocaddr, or something else? */
unsigned long dest_addr; /* Post-relocation address of U-Boot */
dest_addr is the same as relocaddr.
Likewise, dest_addr_sp is the same as start_addr_sp.
It seemed dest_addr/dest_addr_sp was used only as a scratch variable
to calculate relocaddr/start_addr_sp, respectively.
With a little refactoring, we can delete dest_addr and dest_addr_sp.

am335x: enable falcon boot mode for mmc (raw and fat) and nand
Jump into full u-boot mode if a 'c' character is received on the uart.
We need to adjust the spl bss/malloc area to not overlap with the
loadaddr of the kernel (sdram + 32k), so move it past u-boot instead.
For raw mmc, we store the kernel parameter area in the free space after
the MBR (if used). For nand, we use the last sector of the partition
reserved for u-boot.
This also enables the spl command in the full u-boot so the kernel
parameter area snapshot can be created.

spl_mmc: add Falcon mode support for raw variant
If Falcon mode support is enabled (and the system isn't directed into
