AARCH64 : C Model Small Alignment requirements

[Pankaj Bansal <pankaj.bansal@nxp.com>]

Hello Edk2 team,

We are facing a compilation error in our ARMV8 based NXP board.
We are using c model small with GCC49 and GCC5.

"WriteSections64(): %s  due to its size (> 1 MB), this module requires 4 KB section alignment."

With below GCC options, this error is not observed

[BuildOptions]
   GCC:*_*_AARCH64_CC_FLAGS = -mcmodel=small
+  GCC:*_*_AARCH64_DLINK_FLAGS = -z common-page-size=0x1000

My question is, is this necessary to use page size 4K with c model small ?

P.S : This compilation error is not observed with default GCC49/GCC5 options (i.e. C Model tiny and Page Size 0x20)

Thanks & Regards,
Pankaj Bansal
