Merge patch series "BOOTP/DHCPv4 enhancements"
Sean Edmond <seanedmond@microsoft.com> says:
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 introduces 3 improvements to align with RFC 951:
- retransmission backoff interval maximum is configurable
- initial retranmission backoff interval is configurable
- transaction ID is kept the same for each BOOTP/DHCPv4 request
In applications where thousands of nodes are serviced by a single DHCP
server, maximizing the retransmission backoff interval at 2 seconds (the
current u-boot default) exerts high pressure on the DHCP server and
network layer.
RFC 951 “7.2. Client Retransmission Strategy” states that the
retransmission backoff interval should be limited to 60 seconds. This
patch allows the interval to be configurable using the environment
variable "bootpretransmitperiodmax"
The initial retranmission backoff period defaults to 250ms, which is
also too small for these scenarios with many clients. This patch makes
the initial retransmission interval to be configurable using the
environment variable "bootpretransmitperiodinit".
Also, on a retransmission it is not expected for the transaction ID to
change (only the 'secs' field should be updated). Let's save the
transaction ID and use the same transaction ID for each BOOTP/DHCPv4
exchange.

serial driver will then resolve clock frequency from device-tree node parent
clock at init during Main app as it is expected by upstream.

riscv: Access gd with inline assembly when building with LTO or Clang
Similar to AArch64's case, Clang may wrongly fold accesses to gd pointer
which is defined with register qualifier into constants, breaking
various components.
This patch defines gd as a macro when building with Clang or LTO, which
expands to get_gd() that accesses gp pointer in assembly, making RISC-V
ports function properly and preparing for introduction of LTO in the
future. Board initialization code is also adapted for non-assignable gd.

Unlike ARM and X86, booting 32-bit images on 64-bit CPUs is currently
not supported for Risc-V. Hence, for bootm, disallow booting a FIT
or a legacy image that was built for an arch type which is different
than the current arch and for booti, set the arch type to be the
same as the current arch.
