Hi Tapio,

His newer email address that I found with Google is dead, too.
These two object files hold the biggest data objects in the whole
Linux kernel
Basically, these are big arrays of the following structures:
typedef struct _INTEL_HEX_RECORD
{
__u32 length;
__u32 address;
__u32 type;
__u8 data[MAX_INTEL_HEX_RECORD_LENGTH];
} INTEL_HEX_RECORD;
I suggest the following optimizations:
Change structure to
typedef struct _INTEL_HEX_RECORD
{
__u8 type;
__u8 length;
__u16 address;
__u8 data[MAX_INTEL_HEX_RECORD_LENGTH];
} INTEL_HEX_RECORD __attribute__((__packed__));
Store gzip compressed tables and unpack them at load time.
Declare them const and __initdata.
I have a patch somewhere that moves the firmware code to userspace and changes
the drivers to use request_firmware().
Regards,
Clemens
