As my board is not mainlined (still waiting for any review on V5) this doesn't make sense from my point of view.
I just sent a few reviews to one of the patches. As soon as you resubmit this patch, I'll pull the stuff into u-boot-arm and then into mainline.
Here are some numbers:
Test: old (icache) new (i+d cache) image size 191k 204k x 1.06 copy 32MB NOR -> RAM 7.0s 6.5s x 1.07 iminfo of 1.2MiB image 0.5s 0.1s x 5.0 bootm of 1.2MiB gz image 5.4s 0.5s x 10.8 bootm of 0.8MiB lzma image 17.1s 1.5s x 11.4 bootm of 1.6MiB lzo image 3.2s 0.2s x 16.0
The three images have all the same payload. Just tested the three different compression methods.
Boot time limit into application code is 5s so u-boot image compression was not an option. But now it is.
Indeed - that's an impressive set of results. Thanks for the testing.
Best regards,
Wolfgang Denk
