== Boot process ==

Block size = 512 byte

Upon booting, IROM will decide wether to boot internal SD or external SD, based on if the second button from right is held down. If held down, it will boot from external SD.

On a SDHC card, it will boot from 1042 blocks before the end of the card (16 + 1 + 1025), On a SD card this will be on 18 blocks before the end of the card (16 + 1 + 1).

This is where qi is placed, maximum 16 blocks size, zero out the remaining 2/1027 blocks

Qi will then (see /qi/src/cpu/s3c6410/start_qi.c) try to locate a SmartQ firmware image (see genimage for format, or same file, struct FirmHead on 32768 blocks before the end, or 16384 blocks before the end, and load u-boot from the firmware image.

If this fails it will load u-boot from 512+18 blocks before the end, maximum size 512 blocks.

Then, in u-boot (see u-boot/board/samsung/smdk6410/cmd_hhtech.c), it will check first if battery is low and blink LEDS (red) and power off if so (see init_hard_last)

It will then, if a key is pressed:

KEY_UP (+ optional key power): load firmware file from SD, booting kernel + initramfs from it

KEY_LEFT (+ optional key power): load initramfs + kernel from iNAND in similar manner as Qi with FirmHead on 16384.. -- there's no left button on a SmartQ5

KEY_FACTORY (key down + key power): add factory to boot statement

or:

load  kernel from iNAND in similar manner as Qi with FirmHead on 16384/32768

if fail, load initramfs image from SD

== Firmware image format ==

<pre>
typedef struct _firmware_fileheader {
    uint32_t magic;        // '2\0\09'= 0x32 0x00 0x00 0x39
    uint32_t check_sum; // for 8 ~ .fh_size 
    uint32_t fh_size;
    uint32_t version;      // major.minor.revision.xxx, each section in 8-bits
    uint32_t date;          // seconds since the Epoch
    char vendor[32];       // XXX: uint32_t vendor_string_len; char vendor_string[] 
    //uint32_t nand_off_end1=16M/512, nand_off_end2=8M/512;  // offset from INAND END(BLOCKS)
    uint32_t component_count /* = 5*/;
    struct {
        struct {
            uint32_t offset, size; /* nand offset in blocks, sizes and file offset in bytes */ 
        } file, nand;
        uint32_t check_sum;
    }qi, u_boot, zimage, initramfs, rootfs; // components[];
}FirmHead;
</pre>

Offset in NAND is meant as offset from 16/8mb end offset in blocks (512 byte blocks). If offset is 0, it is not meant to be in the NAND image (qi doesn't make any sense there, nor rootfs, etc)
