Blackfin arch: fix bugs in linker script when using upstream binutils

Fix a few problems I discovered when building a kernel with upstream CVS
binutils.

We have to add the NOTES macro to our linker script, since a kernel
built with --build-id is otherwise unable to boot.  Last time NOTES was
added, it broke things, but the definition of the macro has changed not
to rely on parts of the linker script that aren't present on Blackfin.

I also noticed that _l2_lma_start does not point into the kernel image,
but rather somewhere in L1/L2 space, which seems unintended.  Also, when
the L2 section was added to the linker script, the part following it which
computes then length of the init section was not updated.

Blackfin arch: Fix bug - hardware breakpoint doesn't always work in kgdb

Hardware breakpoint doesn't always work in kgdb. It works at the first
two times, but if you repeatedly trigger that hardware breakpoint, it
would slip over that point once in two times.

Fix it by always setting hw bp skip to 0. gdb does skip after hw bp trap.

Bryan Wu [Tue, 18 Nov 2008 09:48:22 +0000]
Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating with positioning a gpio

The whole story:

Before BF51x merged, all the MAX_BLACKFIN_GPIOS are integral multiple of GPIO_BANKSIZE (= 16).
But BF51x provides MAX_BLACKFIN_GPIOS = 40 which includes 3 banks and the 3rd bank has only 8
GPIO pins.

Therefore, gpio_bank() macros is correct when you try to find a GPIO in which bank (GPIO_35 is
in bank 2). But on BF51x gpio_bank(MAX_BLACKFIN_GPIOS) only gives out 2 banks instead of 3
banks for some static array initialization.

This patch add a new macros gpio_bank_n() and GPIO_BANK_NUM to do bank number caculating and
remain the gpio_bank() macros for positioning a gpio in which bank.
