From: David Rivshin <drivs...@allworx.com>
am335x-fb overrides the default lcd_get_size() to add an extra 32 bytes
compared to the normal calculation. While the gd->fb_base is an extra 32
bytes larger than the logical framebuffer size, the first 32 bytes is
always skipped. Adding that extra 32 bytes in lcd_get_size() can cause
check_cache_range() (called from lcd_sync(), via flush_dcache_range()) to
output a warning because the end address is not cacheline aligned, even
if the start and real framebuffer size are.
When removing that "+ 0x20" the am335x-fb lcd_get_size() is identical
to the default one, so just delete it altogether.
