charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org From: Peng Fan The i.MX8M Cortex-M core not has ROM. It has a requirement is the stack, pc value should be set in address 0 and 4 from the view of itself. From Cortex-A core view, the region is at TCML start address. The stack and pc value are the first two words stored in section ".interrupts" of the firmware, and the section is the first section in the firmware. When the firmware is built to run in TCML, there is no issue, because when copying elf segments, the first two words are copied to TCML also. However when the firmware is built ro run in DDR, the first two words are not copied to TCML start address. This patch is to find the ".interrupts" section, read out the first two words and write to TCML start address at offset 0 and 4. If there is no ".interrupts" section, it just return bootaddr.
