cmd: simplify network definitions in Makefile

2024-10-29T18:09:36+00:00

/Makefile already adds lib include paths to UBOOTINCLUDE. There is no point
in adding the same paths again.

Clearly separate the lines relating to NET and to NET_LWIP.

Merge patch series "Allow showing the memory map"

2024-10-25T20:22:36+00:00

Simon Glass  says:

This little series adds a new 'memmap' command, intended to show the
layout of memory within U-Boot and how much memory is available for
loading images.

cmd: Move meminfo command into its own file

2024-10-25T20:22:24+00:00

In preparation for expanding this command, move it into a separate file.
Rename the function to remove the extra underscore. Update the number of
arguments to 1, since 3 is incorrect.

treewide: bcb: move ab_select command to bcb subcommands

2024-10-24T07:45:55+00:00

To enhance code organization, it is beneficial to consolidate all A/B
BCB management routines into a single super-command.
The 'bcb' command is an excellent candidate for this purpose.

This patch integrates the separate 'ab_select' command into the 'bcb'
group as the 'ab_select' subcommand, maintaining the same parameter list
for consistency.

usb: tcpm: add core framework

2024-10-17T01:12:47+00:00

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.

net: lwip: add DHCP support and dhcp commmand

2024-10-16T17:11:56+00:00

Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as
well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due
to this code having an implicit dependency on do_tftpb().

Note that PXE is likely non-fonctional with NET_LWIP (or at least not
100% functional) because DHCP option 209 is not supported by the lwIP
library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled.
