As my board is not mainlined (still waiting for any review on V5) this doesn't make sense from my point of view. > (And it would be nice if you could send some testsresults, how "faster" > let your boot time ;-) 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. Matthias
