[U-Boot] Loading uImage into RAM

[Abdullah YILDIZ]

I'm trying to understand how u-boot loads zImage into RAM.

mkimage is called as

mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008040
-d arch/arm/boot/zImage /bootImage/uImage

Here, 'a' stands for load address and 'e' stands for entry point (64
bytes are used for wrapping?). However, when loading uImage from
u-boot, boot operation starts at address 0x80100000. Furthermore,
u-boot recognizes the load address and entry point as 0x80008000.

Loading from NAND 128MiB 3,3V 8-bit, offset 0x1c0000
  Image Name:   Linux-2.6.27.8
  Image Type:   ARM Linux Kernel Image (uncompressed)
  Data Size:    1735148 Bytes =  1.7 MB
  Load Address: 80008000
  Entry Point:  80008000

## Booting kernel from Legacy Image at 80100000 ...
  Image Name:   Linux-2.6.27.8
  Image Type:   ARM Linux Kernel Image (uncompressed)
  Data Size:    1735148 Bytes =  1.7 MB
  Load Address: 80008000
  Entry Point:  80008000
  Verifying Checksum ... OK
  Loading Kernel Image ... OK

OK

Starting kernel ...

Could you help me with this?
