[U-Boot] qemu x86 ide device not probing automatically with 2018.11

[Joshua Watt]

Hello,

I've been using u-boot as the boot loader for x86 qemu and some custom
(e.g. non-default) boot commands. I recently upgraded from u-boot
2018.01 to 2018.11 and now my boot command fails because it doesn't
look like u-boot is loading the driver for the ide device from which
I'm attempting to load files.

For reference, I'm basically building the qemu-x86 config only with
changes to the default boot scripts. Namely, I have:

 #define CONFIG_BOOTCOMMAND \
	"ide dev ${bootpart}; " \
	"if run loadbootenv; then " \
		"run importbootenv; " \
	"fi; " \
	"run doboot; "

The failure appears to occur when the script attempts to run "ide dev
${bootpart}", claiming the ide device doesn't exist. If I manually run
the command "ide reset", and then "bootd" everything works fine, so I
think this is being caused by the switch to using the device model for
ide(?). I suspect this means that I need to make some changes to my
boot command to get it to probe the ide driver, but I wanted to make
sure I'm doing that the correct way. Should I simply add a "ide reset"
as the first line of CONFIG_BOOTCOMMAND, or is there a more "correct"
way to get u-boot to probe the driver?

Thanks,
