The memory controller could already be enabled, when spd_sdram() is
called. This could be the case for example, when the SDRAM is initialized
by the JTAG debugger.
The "sync" after the register access via the accessor function is
still needed, because the macro uses the sync before the real write
is done. So until not all accesses are converted to using accessor
functions, this sync still needs to be made "manually" here.

We need to track which TLB CAM entries are used to allow us to

The e500mc core supports the ability to stash into the L1 or L2 cache,
however we need to uniquely identify the caches with an id.
We use the following equation to set the various stash-ids:
32 + coreID*2 + 0(L1) or 1(L2)
The 0 (for L1) or 1 (for L2) matches the CT field used be various cache
control instructions.

The header files usb.h and usbdescriptors.h have the same nameed
structure definitions for
usb_config_descriptor
usb_interface_descriptor
usb_endpoint_descriptor
usb_device_descriptor
usb_string_descriptor
These are out right duplicates in usb.h
usb_device_descriptor
usb_string_descriptor
This one has extra unused elements
usb_endpoint_descriptor
unsigned char bRefresh
unsigned char bSynchAddress;
These in usb.h have extra elements at the end of the usb 2.0
specified descriptor and are used.
usb_config_descriptor
usb_interface_descriptor
The change is to consolidate the definition of the descriptors
to usbdescriptors.h. The dublicates in usb.h are removed.
The extra element structure will have their name shorted by
removing the '_descriptor' suffix.
So
usb_config_descriptor -> usb_config
usb_interface_descriptor -> usb_interface
For these, the common descriptor elements are accessed now
by an element 'desc'.
As an example
- if (iface->bInterfaceClass != USB_CLASS_HUB)
+ if (iface->desc.bInterfaceClass != USB_CLASS_HUB)
This has been compile tested on MAKEALL arm, ppc and mips.

Commit c7190f02 (retain POR values of non-configured ACR, SPCR, SCCR,
and LCRR bitfields) moved the LCRR assignment to after relocation
to RAM because of the potential problem with changing the local bus
clock while executing from flash.
This change unfortunately adversely affects the boot time, as running
all code up to cpu_init_r can cause significant slowdown.
E.G. on a 8347 board a bootup time increase of ~600ms has been observed:
0.020 CPU: e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz
0.168 RS: 232
0.172 I2C: ready
0.176 DRAM: 64 MB
1.236 FLASH: 32 MB
Versus:
0.016 CPU: e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz
0.092 RS: 232
0.092 I2C: ready
0.096 DRAM: 64 MB
0.644 FLASH: 32 MB
So far no boards have needed the late LCRR setup, so simply revert it
for now - If it is needed at a later time, those boards can either do
their own final LCRR setup in board code (E.G. in board_early_init_r),
or we can introduce a CONFIG_SYS_LCRR_LATE config option to only do
the setup in cpu_init_r.

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.
This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

This patch moves the s3c24x0 header files from include/ to
include/asm-arm/arch-s3c24x0/.
checkpatch.pl showed 2 errors and 3 warnings. The 2 errors were both due
to a non-UTF8 character in David M?ller's name:
ERROR: Invalid UTF-8, patch and commit message should be encoded in UTF-8
#489: FILE: include/asm-arm/arch-s3c24x0/s3c2410.h:3:
+ * David M?ller ELSOFT AG Switzerland. d.mueller@elsoft.ch
As David's name correctly contains a non-UTF8 character I haven't fixed
these errors.
The 3 warnings were all because of the use of 'volatile' in s3c24x0.h:
WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
#673: FILE: include/asm-arm/arch-s3c24x0/s3c24x0.h:35:
