of packets.

net: Expose some errors generated in net_init

2020-10-10T20:50:12+00:00

net_init does not always succeed, and there is no existing mechanism to
discover errors. This patch allows callers of net_init (such as net_init)
to handle errors. The root issue is that eth_get_dev can fail, but
net_init_loop doesn't expose that. The ideal way to fix eth_get_dev would
be to return an error with ERR_PTR, but there are a lot of callers, and all
of them just check if it's NULL. Another approach would be to change the
signature to something like

int eth_get_dev(struct udevice **pdev)

but that would require rewriting all of the many callers.

net: add a generic udp protocol

2020-09-30T20:55:03+00:00

network loop. So protocol based on udp may be implemented
without modifying the network loop (for example custom
wait magic packet).

net: tftp: Fix load_block offset calculation

2020-09-30T20:48:18+00:00

When load the last block, the "len" might not be a block size. This cause
loading the incorrect last block data.

The fix change "len" to tftp_block_size and minus one tftp_block_size
for offset calculation.

Use same offset calculation formula as in store_block().

net: tftp: Fix store_block offset calculation

2020-09-30T20:48:18+00:00

tftp_cur_block start with 1 for first block, but tftp_cur_block counter is
start with zero when block number is rollover. The existing code
"tftp_cur_block - 1" will cause the block number become -1 in store_block()
when tftp_cur_block is 0 when tftp_cur_block is rollover.

The fix pass in tftp_cur_block to store_block() and minus the
tftp_block_size when do the offset calculation.

fastboot: Add support for 'reboot fastboot' command

2020-09-01T12:47:43+00:00

Android 10 adds support for dynamic partitions and in order to support
this userspace fastboot must be used[1]. New tool fastbootd is
included into recovery.

Userspace fastboot works from recovery and is launched if:
1) - Dynamic partitioning is enabled
2) - Boot control block has 'boot-fastboot' value into command field
The bootloader is expected to load and boot into the recovery image
upon seeing boot-fastboot in the BCB command. Recovery then parses the
BCB message and switches to fastbootd mode[2].

Please note that boot script is expected to handle 'boot-fastboot'
command in BCB and load into recovery mode.

Bootloader must support 'reboot fastboot' command which should reboot
device into userspace fastboot to accomodate those changes[3].

Another command that bootloader must support[3] is 'reboot recovery'. This
command should simply reboot device into recovery mode.
