The first read is only reading the header to see where to load to for
real.  The second read is of the whole file.  See common/spl/spl_fat.c

[U-Boot] Why is u-boot SPL reading u-boot.img twice [Zynq z7c02]?

2014-05-09 Thread Heshsham Abdul Basit 
Hi,

Target: Zynq z7c02

Whenever I run boot.bin generated in TOPDIR/u-boot source  after
compiling u-boot source,

I observe it reads u-boot.img twice:

U-Boot SPL printing from common/spl/spl.c 2014.01-dirty (May 06 2014 - 16:48:05)

mmc boot, reading file arch/arm/cpu/armv7/zynq/spl.c

reading u-boot.img

reading u-boot.img

Why is it reading twice?

Thanks and regards,

Heshsham
