dfu, nand: before write a buffer to nand, erase the nand sectors

before writing the received buffer to nand, erase the nand
sectors. If not doing this, nand write fails. See for
more info here:

http://lists.denx.de/pipermail/u-boot/2013-June/156361.html

Using the nand erase option "spread", maybe overwrite
blocks on, for example another mtd partition, if the
erasing range contains bad blocks.
So a limit option is added to nand_erase_opts()

nand: Don't call adjust_size_for_badblocks for erase

adjust_size_for_badblocks reduces the operation size to account
for the block skipping done by the read/write functions when an
interval (partition name or whole chip) is specified rather than a data
amount.

Erase does not do block skipping, except for erase.spread which takes
a data amount rather than an interval (and thus already does not call
adjust_size_for_badblocks).  Calling adjust_size_for_badblocks when
block skipping is not done means that if bad blocks are present,
the "nand erase.part" and "nand erase.chip" commands will fail to erase

11 years agofsl_esdhc: Do not clear interrupt status bits until data processed

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.

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

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

ARM: tegra: only enable SCU on Tegra20

The non-SPL build of U-Boot on Tegra only runs on a single CPU, and
hence there is no need to enable the SCU when running U-Boot. If an
SMP OS is booted, and it needs the SCU enabled, it will enable the SCU
itself. U-Boot doing so is redundant.

The one exception is Tegra20, where an enabled SCU is required for some
aspects of PCIe to work correctly.

Some Tegra SoCs contain CPUs without a software-controlled SCU. In this
case, attempting to turn it on actively causes problems. This is the case
for Tegra114. For example, when running Linux, the first (or at least
some very early) user-space process will trigger the following kernel
message:

Unhandled fault: imprecise external abort (0x406) at 0x00000000

This is typically accompanied by that process receving a fatal signal,
and exiting. Since this process is usually pid 1, this causes total
system boot failure.
