commit 54652991
Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips
fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads
to problems for smaller versions of this chip e.g. the 32Mbit version
with deviceid 0x16 on mgcoge. So move the code for this work around to
an own function and check previously manufacturer id and device id to
not break other flashes which don't need this work around.

Support for DS1388 is added by extending the DS1337 driver. DS1388 is
similar to DS1337. The time registers are offset by 1 (due to support
for hundreds of seconds), and there is no century bit.
The configuration and trickle charge registers are also different.
Tested on hardware with Freescale P2010 and DS1388.

At the moment, the driver supports the following CPUs:

- ETHER (Fast Ethernet) : SH7724, SH7757
And the driver had the following "#if":
#if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734)
#if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724)
- Those are for GETHER
#if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757)

At least on i.MX25, the RMII mode did not work, which is fixed by this patch.
The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.
According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,
so avoid an invalid assumption. Actually, the choice between half and full
duplex also depends on the endpoint/switch/repeater configuration, so a config
option could be added for that, but there has been no need for it so far.

Buffer coming from upper layers should be cacheline aligned/padded
to perform safe cache operations. For now we don't do bounce
buffering so getting unaligned buffer is an upper layer error.
We can't check if the buffer is properly padded with current
interface so just assume it is (consider changing with in the
future). The following changes are done:
1. Remove useless length alignment check. We get actual transfer
length not the size of the underlying buffer so it's perfectly
valid for it to be unaligned.
2. Move flush_dcache_range() out of while loop or it will
flush too much.
3. Don't try to fix buffer address before calling invalidate:
if it's unaligned it's an error anyway so let cache subsystem
cry about that.
4. Fix end buffer address to be cacheline aligned assuming upper
layer reserved enough space. This is potentially dangerous
operation so upper layers should be careful about that.

The USB spec says that 32 bytes is the minimum required alignment.
However on some platforms we have a larger minimum requirement for cache
coherency. In those cases, use that value rather than the USB spec
minimum. We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and
make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here

This code adds call to mmc_init(), for partition related commands (e.g.

It is safe to call mmc_init() multiple times since mmc->has_init flag
prevents from multiple initialization.
The FAT related code calls get_dev high level method and then uses
elements from mmc->block_dev, which is uninitialized until the mmc_init
(and thereof mmc_startup) is called.

For example, say I set speed to 100K. I'll read back the speed
as 85937. But the speed is really 85937.5, so we I reset
the speed to 85937, I'll get 73660.7. After a couple of transactions
my speed is now exactly 68750 so it will remain there.

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
later device enumeration.

i2c_probe() is changed to reinit the i2c bus upon read failure.
This is naturally the case upon i2c bus probing.
Also, some printf messages upon read failure are removed. As they
would interfere with the "i2c probe" command.
Additionally, i2c_set_bus_speed() now returns 0, so that the
"i2c speed" command can be used.

Add support for the M41T82 RTC to the m41t62 driver. The only
difference that needs to be handled by this driver, is to
clear the HT (Halt Update) bit upon reset. This bit is not
used on the M41T62, so its save to clear this bit always.
The M41T82 support will be used by the X600 (SPEAr600)
board support.

This patch adds the following changes to designware ethernet driver
found on the ST SPEAr SoC:
- Don't init MAC & PHY upon startup. This causes a delay, waiting for
the auto negotiation to complete. And we don't want this delay to
always happen. Especially not on platforms where ethernet is not
used at all (e.g. booting via flash).
Instead postpone the MAC / PHY configuration to the stage, where
ethernet is first used.
- Add possibility for board specific PHY init code. This is needed
for example on the X600 board, where the Vitesse PHY needs to be
configured for GMII mode.
This board specific PHY init is done via the function
designware_board_phy_init(). And this driver now adds a weak default
which can be overridden by board code.
- Use common functions miiphy_speed() & miiphy_duplex() to read
link status from PHY.
- Print status and progress of auto negotiation.
- Print link status (speed, dupex) upon first usage.

There are two problems in the current timeout loop implementation:
1. In case initial test failing, there will always be a delay of 1 ms
2. The delay duration is not tunable
The new implementation addresses both these limitations.
