Current SPL code base has BSS section placed after reset_vector. This means
they have to relocate to use the global variables. This put an implicit

To avoid relocation:

- Modify relocate_code()

Changes:
1. L2 cache is being invalidated by Boot ROM code for e6500 core.
So removing the invalidation from start.S
2. Clear the LAW and corresponding configuration for CPC. Boot ROM
code uses it as hosekeeping area.
3. For Secure boot, CPC is configured as SRAM and used as house
keeping area. This configuration is to be disabled once in uboot.
Earlier this disabling of CPC as SRAM was happening in cpu_init_r.
As a result cache invalidation function was getting skipped in
case CPC is configured as SRAM.This was causing random crashes.

on nand flash using ubi, after the download of the new image into
the flash, the "rest" of the nand sectors get erased while flushing
the medium. With current u-boot version dfu-util may show:
Starting download: [##################################################] finished!
state(7) = dfuMANIFEST, status(0) = No error condition is present
unable to read DFU status
as get_status is not answered while erasing sectors, if erasing
needs some time.
So do the following changes to prevent this:
- introduce dfuManifest state
According to dfu specification
( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
"the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
of the status report by the host. Upon receipt of the anticipated
DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
completes its reprogramming operations."
- when stepping into dfuManifest state, sending a PollTimeout
DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
(dfu-util) waits the PollTimeout before sending a get_status again.

Single-source clocking is new feature introduced in T1040.
In this mode, a single differential clock is supplied to the
DIFF_SYSCLK_P/N inputs to the processor, which in turn is
used to supply clocks to the sysclock, ddrclock and usbclock.
So, both ddrclock and syclock are driven by same differential
sysclock in single-source clocking mode whereas in normal clocking
mode, generally separate DDRCLK and SYSCLK pins provides
reference clock for sysclock and ddrclock
DDR_REFCLK_SEL rcw bit is used to determine DDR clock source
-If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
normal clocking mode by DDR_Reference clock
-If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
single source clocking mode by DIFF_SYSCLK
Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

multi.img
Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB
It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:
$ dumpimage -i multi.img -p 2 System.map
Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is introduced. If "upgrade_available" is
0, "bootcount" is always 0 therefore no need to save the
environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
is incremented in the environment and environment gets written
on u-boot start.
So the Userspace Applikation must set the "upgrade_available"
and "bootcount" variable to 0 (for example with fw_setenv),
if a boot was successfully.

DFU spec mentions it as a method to upgrade firmware (software stored
in writable non-volatile memory). It also says other potential uses of
DFU is beyond scope of the spec.
Here such a beyond the scope use is being attempted - directly pumping
binary images from host via USB to RAM. This facility is a developer
centric one in that it gives advantage over upgrading non-volatile
memory for testing new images every time during development and/or
testing.
Directly putting image onto RAM would speed up upgrade process. This and
convenience was the initial thoughts that led to doing this, speed
improvement over MMC was only 1 second though - 6 sec on RAM as opposed
to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing
DFU framework to avoid multiple copy for ram (if worth) may help, and
on other platforms and other boot media like NAND maybe improvement
would be higher.
And for a platform that doesn't yet have proper DFU suppport for
non-volatile media's, DFU to RAM can be used.
Another minor advantage would be to increase life of mmc/nand as it
would be less used during development/testing.
usage: <image name> ram <start address> <size>
eg. kernel ram 0x81000000 0x1000000
Downloading images to RAM using DFU is not something new, this is
acheived in openmoko also.
DFU on RAM can be used for extracting RAM contents to host using dfu
upload. Perhaps this can be extended to io for squeezing out register
dump through usb, if it is worth.
