DFU spec mentions it as a method to upgrade firmware (software stored
in writable non-volatile memory). It also says other potential uses of
DFU is beyond scope of the spec.
Here such a beyond the scope use is being attempted - directly pumping
binary images from host via USB to RAM. This facility is a developer
centric one in that it gives advantage over upgrading non-volatile
memory for testing new images every time during development and/or
testing.
Directly putting image onto RAM would speed up upgrade process. This and
convenience was the initial thoughts that led to doing this, speed
improvement over MMC was only 1 second though - 6 sec on RAM as opposed
to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing
DFU framework to avoid multiple copy for ram (if worth) may help, and
on other platforms and other boot media like NAND maybe improvement
would be higher.
And for a platform that doesn't yet have proper DFU suppport for
non-volatile media's, DFU to RAM can be used.
Another minor advantage would be to increase life of mmc/nand as it
would be less used during development/testing.
usage: <image name> ram <start address> <size>
eg. kernel ram 0x81000000 0x1000000
Downloading images to RAM using DFU is not something new, this is
acheived in openmoko also.
DFU on RAM can be used for extracting RAM contents to host using dfu
upload. Perhaps this can be extended to io for squeezing out register
dump through usb, if it is worth.

Up till now the DFU maximum file size (to be written to e.g. eMMC)
was different from the DFU data buffer size. It caused errors when
one buffer was smaller than data to be written.
Now, the maximum DFU file size is equal to default DFU buffer size.
In spite of this, user is still able to manually adjust those default
values.

In 5c427e4 we pass BOOTM_STATE_OS_CMDLINE as part of the bootm states to
run, on all arches. However, this is only valid / useful on PowerPC and
MIPS, and causes a problem on ARM where we specifically do not use it.
Rather than make this state fake pass like we do for GO on some arches
(which need updating to use the GO state), we should just not pass
CMDLINE except when it may be used, like before.

The patch fixes the improper read and write of sdhci
host control register for sdma transfer.
The problem comes when reading and writing 1 byte long
host control register with the sdhci_readl() and
sdhci_writel(). The misuse of these functions overwrite
the value of the next registers which are in 4 bytes boundary.
This patch replaces four byte register read/write functions
with one byte read/write ones. Beside, it eliminates
unnecessary bit operation. i.e. or-ing zero against a variable.

In dwmci_prepare_data, the descriptors are allocated for DMA transfer.
These are allocated using the ALLOC_CACHE_ALIGN_BUFFER. This macro uses
the stack to allocate these descriptors. This becomes a problem if the
DMA transfer continues after the processor leaves the function in which
the descriptors were allocated.
Therefore, I have moved the allocated of the buffers up one level, to
dwmci_send_cmd(). The DMA transfer should be complete when leaving this
function.

Netconsole calls eth_halt() before giving control to another operating
system.
But the state machine of netconsole don't take it into account.
Thus, netconsole calls network functions of an halted network device,
making the whole system freeze.
Rather than modifying the state machine of netconsole, we just unregister
the current network device before booting. It does work because
nc_send_packet() verifies that the current network device is not null.

A plain bootm used to call the architecture specific boot function with
no flags, but was modified by commit 35fc84fa "Refactor the bootm
command to reduce code duplication" to call the architecture specific
boot function multiple times with various flags in sequence. The
BOOTM_STATE_OS_CMDLINE flag was not used, indeed it seems that at least
ARM prepares the command line on BOOTM_STATE_OS_PREP. However on MIPS
since commit 59e8cbdb "MIPS: bootm: refactor initialisation of kernel
cmdline" the command line is not prepared in response to a
BOOTM_STATE_OS_PREP flag, only on BOOTM_STATE_OS_CMDLINE or a call with
no flags. The end result is that a combination of those 2 commits leads
to MIPS boards booting kernels with no command line arguments.
An extra invocation of the architecture specific boot function with
BOOTM_STATE_OS_CMDLINE fixes this.

When CONFIG_MMC_SPI is not enabled, the MMC_MODE_SPI capability can
never be set. However there is code in mmc.c which uses the
mmc_host_is_spi macro to check that capability & act accordingly. If we
expand that macro to 0 when CONFIG_MMC_SPI is not set (since it will
always be 0 at runtime anyway) then the compiler can optimize away the
SPI-specific code paths in mmc.c.

"mmc_send_cmd: timeout: No status update" error sometimes happens in
omap_hsmmc driver func mmc_send_cmd() when the MMC controller card
identification and selection sequence is executed for eMMC on OMAP4
boards.
It happens due to incorrect execution of CMD line reset procedure
for OMAP4. Because CMD(DAT) lines reset procedures are slightly
different for OMAP3 and OMAP4(AM335x,OMAP5,DRA7xx).
According to OMAP3 TRM:
Set SRC(SRD) bit in MMCHS_SYSCTL register to 0x1 and wait until
it returns to 0x0.
According to OMAP4(AM335x,OMAP5,DRA7xx) TRMs, CMD(DATA) lines reset
procedure steps must be as follows:
1. Initiate CMD(DAT) line reset by writing 0x1 to SRC(SRD) bit in
MMCHS_SYSCTL register (SD_SYSCTL for AM335x).
2. Poll the SRC(SRD) bit until it is set to 0x1.
3. Wait until the SRC(SRD) bit returns to 0x0
(reset procedure is completed).
Unfortunately, at present omap_hsmmc driver has support only for
OMAP3. And as result step #2 is missing for OMAP4(AM335x,OMAP5,DRA7xx).
This sometimes leads to the fact that the waiting loop which is
required in step #3 does not executed, because SRC bit does not set
yet (at the moment of checking a condition of a loop execution).
And as a result this can cause to timeout error when sending a
next command.
In the particular case (working with eMMC witch do not respond to
some SD specific command) due to incorrect reset sequence after
command SD_CMD_SEND_IF_COND which finished with CTO flag within
64 clock cycles, the next command MMC_CMD_APP_CMD leads to a
timeout error within 1s.
So, extend CMD(DATA) lines reset procedure in func
mmc_reset_controller_fsm() by adding the missing step #2 for
OMAP4+/AM335x boards.
