If board is booted with transitions happening on DCAN1 pins then

This is because DCAN1 module's SWAKEUP mechanism is broken

Makefile:Add GCC flag -fno-delete-null-pointer-checks
-fdelete-null-pointer-checks flag controls global dataflow analyses and
eliminate useless checks for null pointers; It assume that if a pointer is
checked after it has already been dereferenced, it cannot be null.
This flag is enabled by default.
gcc v4.9 has more optimizations added to this option. Hence it is very
aggressive with GCC v4.9 series. Add -fno-delete-null-pointer-checks to

arc: significant cache rework
[1] Align cache management functions to those in Linux kernel. I.e.:
a) Use the same functions for all cache ops (D$ Inv/Flush)
b) Split cache ops in 3 sub-functions: "before", "lineloop" and
"after". That way we may re-use "before" and "after" functions for
region and full cache ops.
[2] Implement full-functional L2 (SLC) management. Before SLC was
simply disabled early on boot. It's also possible to enable or disable
L2 cache from config utility.
[3] Disable/enable corresponding caches early on boot. So if U-Boot is
configured to use caches they will be used at all times (this is useful
in partucular for speed-up of relocation).
arc: implement slave cores kick-start for Linux kernel
With new SMP-enabled CPUs with ARC HS38 cores and corresponding support
in Linux kernel it's required to add basic SMP support in U-Boot.
Currently we assume the one and only core starts execution after
power-on. So most of things in U-Boot is handled in UP mode.
But when U-Boot is used for loading and starting Linux kernel right
before jumping to kernel's entry point U-Boot:
[1] Sets all slave cores to jump to the same address [kernel's entry
point]
[2] Really starts all slav cores
In ARC's implemetation of SMP in Linux kernel all cores are supposed to
run the same start-up code. But only core with ID 0 (master core)
processes further while others are looping waiting for master core to
complete some initialization.
That means it's safe to un-pause slave cores and let them execute kernel
- they will wait for master anyway.
spi, sf: Use offset and size in sf cmd from mtdpartition
With this patch, it is possible to get the offset and size information
from the mtdpartiton setting in "mtdparts", similiar to the
"nand" commandos.
=> sf
sf - SPI flash sub-system
Usage:
sf probe [[bus:]cs] [hz] [mode] - init flash device on given SPI bus
and chip select
sf read addr offset|partition len - read `len' bytes starting at
`offset' to memory at `addr'
sf write addr offset|partition len - write `len' bytes from memory
at `addr' to flash at `offset'
sf erase offset|partition [+]len - erase `len' bytes from `offset'
`+len' round up `len' to block size
sf update addr offset|partition len - erase and write `len' bytes from memory
at `addr' to flash at `offset'
=>
for example "env" is defined in mtdparts:
=> sf read 13000000 env
device 0 offset 0xd0000, size 0x10000
