ARM: 9141/1: only warn about XIP address when not compile testing

2021-11-02T18:46:11Z

commit 48ccc8edf5b90622cdc4f8878e0042ab5883e2ca upstream. In randconfig builds, we sometimes come across this warning: arm-linux-gnueabi-ld: XIP start address may cause MPU programming issues While this is helpful for actual systems to figure out why it fails, the warning does not provide any benefit for build testing, so guard it in a check for CONFIG_COMPILE_TEST, which is usually set on randconfig builds.

vmlinux.lds.h: Move LSM_TABLE into INIT_DATA

2018-10-11T03:40:21Z

Since the struct lsm_info table is not an initcall, we can just move it into INIT_DATA like all the other tables. Signed-off-by: Kees Cook Reviewed-by: Casey Schaufler Reviewed-by: John Johansen Reviewed-by: James Morris Signed-off-by: James Morris

ARM: 8757/1: NOMMU: Support PMSAv8 MPU

2018-05-19T10:53:46Z

ARMv8R/M architecture defines new memory protection scheme - PMSAv8 which is not compatible with PMSAv7. Key differences to PMSAv7 are: - Region geometry is defined by base and limit addresses - Addresses need to be either 32 or 64 byte aligned - No region priority due to overlapping regions are not allowed - It is unified, i.e. no distinction between data/instruction regions - Memory attributes are controlled via MAIR This patch implements support for PMSAv8 MPU defined by ARMv8R/M architecture.

ARM: simplify and fix linker script for TCM

2018-03-10T01:20:43Z

Let's put the TCM stuff in the __init section directly. No need for a separately freed memory area. Remove redundant linker sections, as well as comments that were more confusing than no comments at all. Finally make it XIP compatible by using LOAD_OFFSET in the section LMA specification.

ARM: linker script: factor out TCM bits

2018-03-10T01:20:22Z

This is a plain move with identical results, and therefore still broken in the XIP case. Signed-off-by: Nicolas Pitre Tested-by: Chris Brandt

Move common entries to vmlinux.lds.h as ARM_TEXT. Signed-off-by: Nicolas Pitre Tested-by: Chris Brandt

ARM: linker script: factor out stuff for the DISCARD section

2018-03-10T01:19:35Z

Move common entries to vmlinux.lds.h and leave XIP and non-XIP entries in their respective file. The ARM_NOMMU_KEEP() and ARM_NOMMU_DISCARD() macros are added to be usable within the definition of ARM_DISCARD macro. Signed-off-by: Nicolas Pitre Tested-by: Chris Brandt

ARM: linker script: factor out some common definitions between XIP and non-XIP

2018-03-10T01:19:01Z

Lots of duplications between vmlinux.lds.S and vmlinux-xip.lds.S. This may lead to one file being updated but not the other. For example, SOFTIRQENTRY_TEXT and HYPERVISOR_TEXT were missing from the XIP version. This creates vmlinux.lds.h where a bunch of common defines are moved.
