Mon 18 Feb 2008 06:02:32 PM UTC, original submission:
eeprom_read_block and eeprom_write_block product terrible code when used with a 32-bit variable stored in the register file, since the 32-bit variable must be first copied to the stack, which usually includes adjusting the stack-pointer and allocating a frame-pointer, leading to all sorts of ugly overhead. For this reason, I suggest adding eeprom_read_32 and eeprom_write_32. Simple definitions of these functions follow.
