Re: [U-Boot] [PATCH] ARM: remove bogus cp_delay() function

On 8 June 2017 at 01:48, Lothar Waßmann LW@karo-electronics.de wrote:

The cp_delay() function was introduced because of a missing 'volatile' attribute to the 'asm' statement in get_cr() which led to the 'mrc' instruction in get_cr() being optimised out eventually. This has been fixed in commit 53fd4b8c22bb ("arm: mmu: Add missing volatile for reading SCTLR register") but the bogus cp_delay() function which was introduced as a workaround for the malfunctioning get_cr() was never removed.
