On certain platforms it does not make sense to generate
|
||||
TF-A binary images. For example a platform could make use of serveral
|
||||
memory areas, which are non-continuous and the resulting binary
|
||||
therefore would suffer from the padding-bytes.
|
||||
Typically these platforms use the ELF image.
|
||||
|
||||
This patch introduces a variable DISABLE_BIN_GENERATION, which
|
||||
can be set to '1' in the platform makefile to prevent the binary
|
||||
generation.

Subject: [PATCH 2/2] rockchip: Disable binary generation for all SoCs.
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
All supported Rockchip SoCs (RK3288, RK3328, RK3368 and RK3399)
|
||||
have non-continuous memory areas in the linker script with a huge
|
||||
gap between them. This results in extremely padded binary images
|
||||
with a size of about 4 GiB.
|
||||
|
||||
E.g. on the RK3399 we have the following memory areas (and base addresses):
|
||||
RAM (0x1000), SRAM (0xFF8C0000), and PMUSRAM (0xFF3B0000).
|
||||
|
||||
Consumers of the TF-A project (e.g. coreboot or U-Boot) therefore
|
||||
use the ELF image instead, which has a size of a few hundred kBs.
|
||||
|
||||
In order to prevent the generation of a huge and useless file,
|
||||
this patch disables the binary generation for all affected Rockchip
|
||||
SoCs.
