From: Simon Glass <simon.glass@canonical.com> Add a Boot Loader Specification (BLS) Type #1 bootmethod, enabling U-Boot to discover and boot from BLS entry files. This is used by Fedora, RHEL and other distributions. The series also extends PXE infrastructure to support multiple initrd files using an alist, with LMB-based memory allocation for placing subsequent initrds. The sysboot command gains the same LMB allocation support. Finally, a 'fit' field is added as a U-Boot extension to the BLS format, allowing entries to explicitly specify a FIT image path as an alternative to the 'linux' field. It also includes a fix for a long-standing linker-list bug, as well as a recently introduced Kconfig warning.
