Hi Albert,
+asm ("\n\
A file scope asm?! Please don't.
+ * We enter with the cache enabled, the MMU enabled and some known
legacy
+ * memory mappings active. xBAT3 is unused
It would be good if you could depend as little as possible on these
things;
that makes writing another bootloader a lot easier.
+ /* IBAT3,DBAT3 for first 16Mbytes */\n\
+ li 8, 0x01ff /* 16MB */\n\
+ li 9, 0x0002 /* rw */\n\
+ mtspr 0x216, 8 /* IBAT3U */\n\
+ mtspr 0x217, 9 /* IBAT3L */\n\
+ mtspr 0x21e, 8 /* DBAT3U */\n\
+ mtspr 0x21f, 9 /* DBAT3L */\n\
WIMG=0000, are you sure? Not M=1?
+ bcl- 20,4*cr7+so,1f\n\
Just write bcl 20,31,1f .
