From 163fb376695661620f13839ec35d860e7e7ff504 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 10 Oct 2022 18:01:20 +0100 Subject: [PATCH] qfw: store loaded file size in environment variable At the moment the QEMU firmware command just prints the size of the loaded binaries on the console. To go with all the other load methods, and many boot scripts' expectations, also store the size of the file loaded last in the environment variable "filesize". We first put the kernel size in there, but overwrite this with the initrd size, should we have one, because this is probably the more prominent user of $filesize (in the booti or bootz command).
