ARM: 8639/1: Define KERNEL_START and KERNEL_END
In preparation for adding CONFIG_DEBUG_VIRTUAL support, define a set of common constants: KERNEL_START and KERNEL_END which abstract CONFIG_XIP_KERNEL vs. !CONFIG_XIP_KERNEL. Update the code where relevant. Acked-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
