983c72f479 Clarify bootm OS arguments
At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.

1865286466 Introduce generic link section.h symbol files
We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.

Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.

One change is needed in arch/avr32/lib/board.c to make this conversion
work.

5cb48582ac Add architecture-specific global data
We plan to move architecture-specific data into a separate structure so
that we can make the rest of it common.

As a first step, create struct arch_global_data to hold these fields.
Initially it is empty.

This patch applies to all archs at once. I can split it if this is really
a pain.

3874a37745 openrisc: Work around potential relocation issues
When reset code is in flash, the jump instructions emitted by the
compiler are relative instead of absolute jumps.

A fix to the reset code to make correct jumps to the beginning of
code relocated to RAM have also been added.

47fde91f0c global_data: unify global flag defines
All the global flag defines are the same across all arches.  So unify them
in one place, and add a simple way for arches to extend for their needs.

50a47d0523 net: punt bd->bi_ip_addr
This field gets read in one place (by "bdinfo"), and we can replace
that with getenv("ipaddr").  After all, the bi_ip_addr field is kept
up-to-date implicitly with the value of the ipaddr env var.
