When CONFIG_OF_HAS_PRIOR_STAGE is enabled and fdtfile is not set, efi_get_distro_fdt_name() returns -EALREADY to indicate the prior-stage FDT should be used. The block-device EFI path handles this by setting BOOTFLOWF_USE_PRIOR_FDT, but the network path treats it as an error, causing the bootflow to stay in 'base' state with a -EALREADY error. This also means fdt_addr_r is required even when no FDT download is needed, giving a spurious -EINVAL error. Fix this by calling efi_get_distro_fdt_name() before checking fdt_addr_r, and handling -EALREADY by setting BOOTFLOWF_USE_PRIOR_FDT to skip the FDT download, matching the block-device behaviour. THere is no test for this at present, since sandbox does not enable CONFIG_OF_HAS_PRIOR_STAGE and lacks infra for network-based EFI boot. Signed-off-by: Simon Glass <sjg@chromium.org>
