This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

JEDEC spec allows DRAM vendors to use prime DQ for write leveling. This
is not an issue unless some DQ pins are not connected. If a platform uses
regular DIMMs but with reduced DDR ECC pins, the prime DQ may end up on
those floating pins for the second rank. The workaround is to use a known
good chip select for this purpose.

registers, which are included in the MDIO register block
common to Freescale ethernet controllers. So it shouldn't
depend on the CPU architecture but it should be actually
part of the arch independent fsl_mdio.h.
To remove the arch dependency, merge the content of

This commit provides distinction between DFU device detach and reset.
The -R behavior is preserved with proper handling of the dfu-util's -e
switch, which detach the DFU device.
By running dfu-util -e; one can force device to finish the execution of
dfu command on target and execute some other scripted commands.
Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.
It was also necessary to increase the number of usb_gadget_handle_interrupts()
calls since we also must wait for detection of the USB reset event.
Example usage:
1. -e (detach) switch
dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e
access to u-boot prompt.
2. -R (reset) switch
dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage
target board reset

We noticed on the DXR2 platform (AM335x with a SMSC LAN9303 switch connected
to the CPSW MAC) that the network performance in U-Boot is quite poor. Only
when the transfer is started without a cable connected, and the cable is
plugged after the first timeout "T" occured, an increased in performance
can be seen. Debugging has revealed, that the cpsw driver has constant
link checking builtin into the rx and tx functions. This results in the
bad performance and seems to be unnecessary. The link has already been
checked in the init function, before the transfer is started. This usually
is sufficient.
BTW: I have seen no other network driver in U-Boot so far, that constantly
checks for link in the rx / tx functions.
The performance numbers on the DXR2 board are:
0.56 MiB/s cpsw_check_link() in rx and tx path
0.87 MiB/s cpsw_check_link() only in tx path
1.0 MiB/s cpsw_check_link() only in rx path
2.7 MiB/s no cpsw_check_link() in rx and tx path
So with this patch the network performance on DXR2 increases from 0.56
to 2.7 MiB/s (nearly 5 times as fast).

XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs
of serdes2 are routed to a SFP+ cages, which to house fiber cable or
direct attach cable(copper), the copper cable is used to emulate the
10GBASE-KR scenario.
So, for XFI usage, there are two scenarios, one will use fiber cable,
another will use copper cable. For fiber cable, there is NO PHY, while
for copper cable, we need to use internal PHY which exist in Serdes to
do auto-negotiation and link training, which implemented in kernel.
We use hwconfig to define cable type for XFI, and fixup dtb based on the
cable type.
For copper cable, set below env in hwconfig:
fsl_10gkr_copper:<10g_mac_name>
the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The
four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports,
if a given 10G port will use the copper cable for 10GBASE-KR, set the
<10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be
assumed to be used for the port.
For ex. if four XFI ports will both use copper cable, the hwconfig
should contain:
fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2
For fiber cable:
1. give PHY address to a XFI port, otherwise, the XFI ports will not be
available in U-boot, there is no PHY physically for XFI when using fiber
cable, this is just to make U-boot happy and we can use the XFI ports
in U-boot.
2. fixup dtb to use fixed-link in case of fiber cable which has no PHY.
Kernel requests that a MAC must have a PHY or fixed-link.
When using XFI protocol, the MAC 9/10 on FM1 should init as 10G interface.
Change serdes 2 protocol 56 to 55 which has same feature as 56 since 56
is not valid any longer.
