Changes in v8: None
Changes in v7: None
Changes in v6:
- add docbook comments
- rename fastboot_download_data() to fastboot_data_download(), rename
fastboot_get_bytes_remaining() to fastboot_data_remaining()
- split fastboot_data_complete() out from fastboot_data_download() so we
can call it at the end of the transfer phase for USB
Changes in v5:
- make fastboot_bytes_received/expected static and add function
fastboot_get_bytes_remaining()
- move fastboot_buf_addr/fastboot_buf_size/fastboot_progress_callback
into fastboot-internal.h
- delete redundant fb_ prefixes from statics
Changes in v4:
- guard fb_getvar/fb_command with UDP_FUNCTION_FASTBOOT in Makefile
- add docbook comments
- remove parameter from fastboot_boot() since we always want
fastboot_buf_addr (and if we're using fastboot_bootcmd then it's
ignored)
- split oem format into new patch
Changes in v3:
- use FASTBOOT as our guard in Kconfig not a list of USB || UDP
- correct mis-translation from AOSP introduced when cleaning up for
checkpatch - we should write when buffer is not NULL, rather than
erasing, and erase when buffer is NULL
- use CMD_RET_USAGE from do_fastboot
- remove do_fastboot_udp from cmd/net.c and rewrite using net_loop()
- rename timed_send_info to fastboot_send_info, rename fastboot_send_info to
fastboot_udp_send_info
- replace FASTBOOT_HEADER_SIZE with sizeof(struct fastboot_header)
- move start time into timed_send_info() rather than passing it in
- make calls to fastboot_udp_send_info a runtime dependency, not a compile
time one
- set ${filesize} to size of downloaded image
- add progress meter from USB path during download
- add support for 'oem format' command from the USB path
- rename 'fastbootcmd' to 'fastboot_bootcmd' to make clear that this is the
fastboot boot command
- make getvar implementation table driven
- add fastboot_buf_addr, fastboot_buf_size to override buffer address and
size
- return correct filesystem type in getvar partition-type on MMC
- process "fastboot." prefixed env variables in getvar first so you
can override the normal values (this also lets you set a fs type for
NAND devices)
- squash subsequent patches which change this code into this one:
- If the fastboot flash/erase commands are disabled, remove that support
so we still build correctly.
- Add NAND support to fastboot UDP flash/erase commands
- If we don't have a partition name passed, report it as not found.
- Change the behaviour of the fastboot net code such that
"reboot-bootloader" is no longer written to CONFIG_FASTBOOT_BUF_ADDR for
use as a marker on reboot (the AOSP code in common/android-bootloader.c
uses this marker - this code could be reinstated there if that gets
merged).
- Merge USB and UDP boot code. The USB implementation stays the same, but
UDP no longer passes an fdt. We introduce a new environment variable
'fastboot_bootcmd' which if set overrides the hardcoded boot command,
setting this then allows the UDP implementation to remain the same. If
after running 'fastboot_bootcmd' the board has not booted, control is
returned to U-Boot and the fastboot process ends.
- Separate the fastboot protocol handling from the fastboot UDP code in
preparation for reusing it in the USB code.
Changes in v2:
- ensure fastboot syntax is backward compatible - 'fastboot 0' means
'fastboot usb 0'
