simple task to speed up booting

2014-12-14 Thread Poul-Henning Kamp
The rotating swirlie ('-/|\') in the loader accounts for a surprisingly large part of our boot time on systems with slow-ish serial consoles. I think right now it takes a step for each 512 byte read, reducing that to once every 64kB or even 1MB would be an improvement with the kind of kernel sizes
