Subject: [U-Boot] Very slow fatload on bcm2835
Date: Thu, 11 Jun 2015 20:35:14 +0200	[thread overview]
Message-ID: <20150611203514.2f83d4b3@north> (raw)

Hello!

I'm using latest git source of U-Boot on Raspberry Pi Compute Module 
and performance of fatload is quite bad.  Does anyone have any clue
about what can be wrong?  Is it the lack of cache?

Sample boot log:

U-Boot 2015.07-rc2-dirty (Jun 11 2015 - 17:03:17 +0200)

Thanks!
