[U-Boot] [PATCH] drivers: block: Allow to cache 4K blocks by default

[Jan Kiszka]

The default settings of the block cache so far only allow to hold single
1K blocks. However, larger filesystems tend to use 4K. Failing to cache
those massively degrades access performance unless you manually tune the
cache first. This is not desirable.

My "load mmc is slow" problem reappeared on AM65xx after growing the
rootfs to almost 1 GB - despite an active block cache.
