From 68812bb23359d7ad27d5c011589cf2c91874cdcf Mon Sep 17 00:00:00 2001 From: Tim Gover Date: Wed, 16 Feb 2022 09:46:58 +0000 Subject: [PATCH] bootloader: Remove redudant date information Drop explicit references to pre-2021 bootloader releases because there's been two default releases since then. The older releases aren't supported because they won't work on all Pi variants. --- .../computers/raspberry-pi/bcm2711-bootloader.adoc | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) diff --git a/documentation/asciidoc/computers/raspberry-pi/bcm2711-bootloader.adoc b/documentation/asciidoc/computers/raspberry-pi/bcm2711-bootloader.adoc index 0ff2a593a..0dd48211c 100644 --- a/documentation/asciidoc/computers/raspberry-pi/bcm2711-bootloader.adoc +++ b/documentation/asciidoc/computers/raspberry-pi/bcm2711-bootloader.adoc @@ -2,7 +2,7 @@ === Editing the Configuration -Before editing the bootloader configuration, xref:os.adoc#updating-and-upgrading-raspberry-pi-os[update your system] to get the latest version of the `rpi-eeprom` package.
