[PATCH v10 0/9] Add EFI HTTP boot support
This series adds the EFI HTTP boot support. User can add the URI device path with "efidebug boot add" command. efibootmgr handles the URI device path, download the specified file using wget, mount the downloaded image with blkmap, then boot with the default file(e.g. EFI/BOOT/BOOTAA64.EFI) by selecting automatically created boot option when the new disk is detected.
This version still does not include the test.
To enable EFI HTTP boot, we need to enable the following Kconfig options. CONFIG_CMD_DNS CONFIG_CMD_WGET CONFIG_BLKMAP CONFIG_EFI_HTTP_BOOT
On the Socionext Developerbox, enter the following commands then debian installer is downloaded into "loadaddr" and installer automatically starts. => dhcp => setenv serverip 192.168.1.1 => efidebug boot add -u 3 debian-netinst http://ftp.riken.jp/Linux/debian/debian-cd/12.1.0/arm64/iso-cd/debian-12.1.0... => efidebug boot order 3 => bootefi bootmgr
Note that this debian installer can not proceed the installation bacause RAM disk of installer image is not recogniged by the kernel. I'm still investigating this issue, but drivers/nvdimm/of_pmem.c in linux will be one of the solution to recognize RAM disk from kernel. (In EDK2, the equivalent solution is called ACPI NFIT.)
On QEMU, I can not make DNS work from the QEMU guest. The following commands work on qemu_arm64(manually set the http server ip in URI). => dhcp => setenv gatewayip 10.0.2.2 => setenv httpserverip 134.160.38.1 => efidebug boot add -u 3 debian-netinst http://134.160.38.1/Linux/debian/debian-cd/12.1.0/arm64/iso-cd/debian-12.1.0... => efidebug boot order 3 => bootefi bootmgr
[TODO] - add test - stricter wget uri check - omit the dns process if the given uri has ip address -> this will be supported when the lwip migration completes - uri device path support in eficonfig - expose ramdisk to OS
[change log] v9 -> v10 - fix failure in erofs python test - refactor try_load_from_uri_path(), call efi_load_image() in single location - missing free of file_path for EFI application - fix blkmap_create_ramdisk() size type from int to ulong
v8 -> v9 - implement new EFI event to notify that loaded image returns and back to the efibootmgr - ramdisk cleanup is done in event callback - refactor error handling
v7 -> v8 - search the default file on the fly, instead of creating the boot option with default file - delete blkmap and reserved memory in case of error or when the EFI application returns - update the subject "Boot var automatic management for removable medias" since this automatic boot option management is also applied for non-removable medias - update error handling in efidebug command - call efi_add_memory_map() instead of exposing efi_reserve_memory()
v6 -> v7 - rename the funtion name from load_default_file_boot_option() to load_mounted_image() - move some fix from patch #5 "efi_loader: support boot from URI device path" to patch #4 "efi_loader: create default file boot option". - fix missing free() of default_file_path
v5 -> v6 - add patch #4 "Boot var automatic management for removable medias" - boot from automatically created boot option rather than searching default file on the fly - introduce new CONFIG_EFI_HTTP_BOOT Kconfig option - comment in one place - use log_err() rather than printf() - use env_get_hex("filesize", 0) instead of return value of net_loop() - use more suitable error code - blkmap can be build for SPL/TPL - add CDROM short-form device path support
v4 -> v5 - add missing else statement - add NULL check of efi_dp_find_obj() call - update document to remove "limitation"
v3 -> v4 - patch#8 is added to simplify the bootmgr default boot process - add function comments
v2 -> v3 - Patch#6 is added, reserve the whole ramdisk memory region - remove .efi file extension check for PE-COFF image - use "if IS_ENABLED(..)" as much as possible - 1024 should be sizeof(net_boot_file_name) - call net_set_state(NETLOOP_FAIL) when wget encounters error - describe DNS ip address host name limitation in document
v1 -> v2 - carve out the network handling(wget and dns code) under net/wget.c - carve out ramdisk creation code under drivers/block/blkmap_helper.c - wget supports the valid range check to store the received blocks using lmb - support when the downloaded image have no partiton table but a file system - not start the .efi file in try_load_entry() - call efi_check_pe() for .efi file to check the file is PE-COFF image - add documentation for EFI HTTP Boot

This introduces the valid range check to store the received blocks using lmb. The same logic is implemented in tftp.

Current wget takes the target uri in this format: "<http server ip>:<file path>" e.g.) 192.168.1.1:/bar The http server ip address must be resolved before calling wget.
This commit adds the utility function runs wget with dhs. User can call wget with the uri like "http://foo/bar".

User needs to call several functions to create the ramdisk with blkmap. This adds the utility function to create blkmap device and mount the ramdisk.
