Oops, that was my mistake. The txx9_irq_init() assumes its baseaddr
can be remapped without TLB. This is true but plat_ioremap for
jmr3927 was wrong.
Could you try this patch? (can be used for 2.6.23 and current git)
Subject: [MIPS] Fix plat_ioremap for JMR3927
TX39XX's "reserved" segment in CKSEG3 area is 0xff000000-0xfffeffff.
