5 * Patch by Anders Larsen, 09 Jan 2004:
7 ARM memory layout fixes: the abort-stack is now set up in the
8 correct RAM area, and the BSS is zeroed out as it should be.
10 Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
11 of the linker scripts are replaced by '__bss_start' and '_end',
12 resp., which is a further step to eliminate unnecessary differences
13 between the implementation of the CPU architectures.

1029 o correctly extends the timeout depending on the size of all
1030 queued messages for both transmit and receive
1031 o will not continue with receive if transmit times out
1032 o ensures that the error callback is done for all queued tx
