Ralf,
>From the change 1.42 to 1.43 on file arch/mips/kernel/traps.c some code was
added
to copy the EJTAG exception vector
+ /*
+ * Copy the EJTAG debug exception vector handler code to it's final
+ * destination.
+ */
+ memcpy((void *)(KSEG0 + 0x300), &except_vec_ejtag_debug, 0x80);
This code indescriminatly smashes the end of except_vec0_r4600 and
all of except_vec0_nevada handlers with the .fill set to only 0x280
00000000800002d4 T except_vec0_r4600
0000000080000328 T except_vec0_nevada
0000000080000380 T except_vec0_r45k_bvahwbug
I'm not sure under what platform we need to load JTAG support, but we can
just increase the fill area in head.S to say 0x400
Cheers
Liam
