on my board U-Boot should program an FPGA before booting linux. Unfortunatly the
file is quite big (>160KB). So I store a gzipped version of it in my flash.
Actually I stored an image created with mkimage
DAB4K2> imi 40040000
## Checking Image at 40040000 ...
Image Name: DAB4K_TEST-
Created: 2003-09-22 8:20:19 UTC
Image Type: PowerPC U-Boot Firmware (gzip compressed)
Data Size: 56098 Bytes = 54.8 kB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
So what I need now is a way to uncompress the data to RAM before I can call
1. Should we add a "gunzip" command to U-Boot?
2. Should we add a command (similar to bootm) that takes an image, decompresses
it and checks CRC etc.?
3. Or should we put this into the "fpga load" command?
I would go for the first. Maybe the second. Third seems to be too limited.
