# Note: SYSTEM, ZTEXTADDR, ZBSSADDR and ZRELADDR are exported |
|---|
| 7 |
# from arch/mips/boot/Makefile. Their meanings are as follows: |
|---|
| 8 |
# |
|---|
| 9 |
# ZTEXTADDR |
|---|
| 10 |
# Start address of decompressor. You normally call the kernel |
|---|
| 11 |
# at this address to start it booting. This doesn't have |
|---|
| 12 |
# to be located in RAM, it can be in flash or other read-only or |
|---|
| 13 |
# read-write addressable medium. It should be an address in kseg1. |
|---|
| 14 |
# |
|---|
| 15 |
# ZBSSADDR |
|---|
| 16 |
# Start address of zero-initialised work area for the decompressor. |
|---|
| 17 |
# This must be pointing at RAM. The decompressor will zero initialise |
|---|
| 18 |
# this for you. It should be an address in kseg1 too. The default for |
|---|
| 19 |
# this is to place it just after the image (so when running the code |
|---|
| 20 |
# from ROM you will need to set this to something useful). |
|---|
| 21 |
# |
|---|
| 22 |
# ZRELADDR |
|---|
| 23 |
# This is the address where the decompressed kernel will be written, |
|---|
| 24 |
# and eventually executed. It will be in kseg0. |
|---|
