In our datacenter application, a single DHCP server is servicing 36000+ clients.
Improvements are required to the DHCPv4 retransmission behavior to align with
RFC and ensure less pressure is exerted on the server:
- retransmission backoff interval maximum is configurable
(environment variable bootpretransmitperiodmax)
- initial retransmission backoff interval is configurable
(environment variable bootpretransmitperiodinit)
- transaction ID is kept the same for each BOOTP/DHCPv4 request
(not recreated on each retry)
For our application we'll use:
- bootpretransmitperiodmax=16000
- bootpretransmitperiodinit=2000
A new configuration BOOTP_RANDOM_XID has been added to enable a randomized
BOOTP/DHCPv4 transaction ID.
Enhance DHCPv4 sending/parsing option 209 (PXE config file). A previous
patch was accepted. A new patch fixes a possible double free() and
addresses latest review comments.

This patch series introduces the fuse writebuff sub-system command and
makes improvements to the existing fuse implementation by removing the
custom string functions. The patches are required to be applied in
sequence.
The series consists of the following changes:
Patch 1 removes custom string functions and replaces them with standard
string functions.
Patch 2 introduces fuse.rst documentation for fuse commands.
Patch 3 introduces the fuse writebuff sub-system command, allowing to
write a structured buffer in memory to fuses, and implementing the
necessary function calls.
Patch 4 enables the fuse sub-system in the K3 platform.
Patch 5 updates the fuse.rst documentation to include details about the
new fuse writebuff command.
These changes aim to improve the fuse sub-system by the removal of
custom string functions and the addition of the fuse writebuff
command improves fuse programming workflows by allowing to write a

To help out Kconfig we can simplify the if conditions, so that the

contains all network command options. We can also remove nested checks
for CMD_NET or (NET || NET_LWIP).

Ultimately the 'bootflow info' command may change to also show images as

This adds TCPM framework in preparation for fusb302 support, which can
handle USB power delivery messages. This is needed to solve issues with
devices, that are running from a USB-C port supporting USB-PD, but not
having a battery.
Such a device currently boots to the kernel without interacting with
the power-supply at all. If there are no USB-PD message replies within
5 seconds, the power-supply assumes the peripheral is not capable of
USB-PD. It usually takes more than 5 seconds for the system to reach
the kernel and probe the I2C based fusb302 chip driver. Thus the
system always runs into this state. The power-supply's solution to
fix this error state is a hard reset, which involves removing the
power from VBUS. Boards without a battery (or huge capacitors) will
reset at this point resulting in a boot loop.
This imports the TCPM framework from the kernel. The porting has
originally been done by Rockchip using hardware timers and the Linux
kernel's TCPM code from some years ago.
I had a look at upgrading to the latest TCPM kernel code, but that
beast became a lot more complex due to adding more USB-C features.
I believe these features are not needed in U-Boot and with multiple
kthreads and hrtimers being involved it is non-trivial to port them.
Instead I worked on stripping down features from the Rockchip port
to an even more basic level. Also the TCPM code has been reworked
to avoid complete use of any timers (Rockchip used SoC specific
hardware timers + IRQ to implement delayed work mechanism). Instead
the delayed state changes are handled directly from the poll loop.
Note, that (in contrast to the original Rockchip port) the state
machine has the same hard reset quirk, that the kernel has - i.e.
it avoids disabling the CC pin resistors for devices that are not
self-powered. Without that quirk, the Radxa Rock 5B will not just
end up doing a machine reset when a hard reset is triggered, but will
not even recover, because the CPU will loose power and the FUSB302
will keep this state because of leak voltage arriving through the RX
serial pin (assuming a serial adapter is connected).
This also includes a 'tcpm' command, which can be used to get
information about the current state and the negotiated voltage
and current.
