[RFC] ARM: spear: remove spear13xx_secondary_startup from INIT section.

[Srinivas KANDAGATLA]

From: Srinivas Kandagatla <srinivas.kandagatla at st.com>

This patch removes spear13xx_secondary_startup fromm _INIT section, there are
two  reasons for this removal.
 1. discarding such a small code does not save much, given the RAM sizes.
 2. Having this code discarded, creates corruption issue when we boot
smp-kernel with nr_cpus=1 or with single cpu node in DT.

Hi,

I did encounter corruption issues on STi CA9 SOCs when a SMP kernel is booted with
nr_cpus=1. This boiled down to freeing the __INIT section of the secondary
startup code. It looks like two other SOCs(Spear and ux500) might have same
issue.

Do you think this patch is valid for Spear?

Thanks,
srini
