- Timeout counter value is set as DTOCV bits in SYSCTL register
For counter value set as timeout,
Timeout period = (2^(timeout + 13)) SD Clock cycles
- As per 4.6.2.2 section of SD Card specification v2.00, host should
cofigure timeout period value to minimum 0.25 sec.
- Number of SD Clock cycles for 0.25sec should be minimum
(SD Clock/sec * 0.25 sec) SD Clock cycles
= (mmc->tran_speed * 1/4) SD Clock cycles
- Calculating timeout based on
(2^(timeout + 13)) >= mmc->tran_speed * 1/4
Taking log2 both the sides and rounding up to next power of 2
=> timeout + 13 = log2(mmc->tran_speed/4) + 1

Port USB gadget RNDIS protocol support from linux-2.6.26
(.27 gadget stack actually has composite drivers).
Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
Disconnecting USB gadget with pending interrupt may cause its wrong
handling in the next time when interface will be started again
(especially actual for RNDIS). This interrupt may force the gadget
to queue unexpected response before setup stage.
Despite the fact that such interrupt handled after dropped pullup
also may add pending response, this will not bring to any issues due to
usb_ep_disable (which clears the queue) called on gadget unregistering.

This adds support for using USB Ethernet dongles in host mode. This is just

Changed both to use a common timeout for URB submission, since they were using
different values and EHCI's was too short.
Also fixed EHCI to actually check if urb submission succeeded, rather than
silently continuing into the weeds.

The MXC SPI driver didn't calculate the SPI clock up to
now and just used highest possible divider 512 for DATA
RATE in the control register. This results in very low
transfer rates.
The patch adds code to calculate and setup the SPI clock
frequency for transfers.

We need to shift only one time in each cycle in the swapping loop
for unaligned tx case. Currently two byte shift operations are
performed in each loop cycle causing zero gaps in the transmited
data, so not all data scheduled for transmition is actually
transmited.
The proper swapping in unaligned rx case is missing, so add it
as we need to put the received data into the rx buffer in the
correct byte order.

The patch adds helper funtions for basic access to the registers
of the MC9sdz60 chip (multifunctional device with RTC and CAN) via
I2C interface.
Signed-off-by: Stefano Babic <sbabic@denx.de>
There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).
The current driver uses the IIF bit in the status register
to check if the bus is busy or not. According to the manual,
this is not correct, because the IIB bit should be checked.
Not only, to check if a transfer is finished must be checked
the ICF bit, and this is not tested at all.
This patch comes from analyse with a corresponding driver
provided by Freescale as part of the LTIB tool. Comparing
the two drivers, it appears that the current u-boot driver checks
the wrong bits, and depending on race condition, the transfer
can be successful or not.
The patch gets rid also of own debug function (DPRINTF),
replaced with the general debug().
Tested on Freescale mx35pdk.
