MIPS: reserve space for exception vectors 2016-11-30T15:11:46+00:00 Daniel Schwierzeck daniel.schwierzeck@gmail.com 2016-01-09T17:34:14+00:00 bd60252811c3c81dd0a32c0871b9116ba160190f In order to set own exception handlers, a table with the exception vectors must be built in DRAM and the CPU EBase register must be set to the base address of this table. Reserve the space above the stack and use gd->irq_sp as storage for the exception base address. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> 
In order to set own exception handlers, a table with the exception
vectors must be built in DRAM and the CPU EBase register must be
set to the base address of this table.

Reserve the space above the stack and use gd->irq_sp as storage
for the exception base address.
