From 80a7f4e7b6abd956ea9e73387b47a2fd0e33f14b Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Tue, 11 Jan 2022 12:54:36 -0700 Subject: console: Add Kconfig to dump pre-bootblock cbmem contents Pre-bootblock stages (i.e., VBOOT_STARTS_BEFORE_BOOTBLOCK) might not have the ability to log to the UART, so their console messages are inaccessible until the boot processes gets into the payload or OS. This makes it difficult to debug verstage. This feature will dump the pre-bootblock CBMEM console immediately after the bootblock console is initialized. I chose to do this in console_init instead of bootblock_soc_init because I wanted to have the pre-bootblock contents dumped before the coreboot bootblock starting message is printed. BUG=b:213828947 TEST=Boot guybrush with PSP verstage and verify verstage logs are dumped to the UART.
