treewide: move bi_dram[] from bd to gd

2026-06-25T00:13:24Z

Currently, the bi_dram[] information is stored in the board info structure (bd). Because bd is only valid after reserve_board(), dram_init_banksize() must be called late in the initialization process. This limitation is problematic, as it forces us to rely on a variety of bespoke functions to determine board RAM, bank memory sizes, and other early setup requirements. By moving bi_dram[] into the global data (gd), we can run it earlier. This is particularly convenient since boards define their own dram_init_banksize() routines, which do not always rely on parsing Device Tree (DT) memory nodes. Additionally, U-Boot defaults to relocating to the top of the first memory bank. While boards currently use custom functions to override this behavior, having the DRAM bank information available earlier in gd makes relocating to a different bank trivial and standardizes the process.

cmd: ufetch: only show comma separator if there was a previous feature

2026-05-18T09:04:14Z

Currently, if NET is disabled, the next feature to be printed will start with a comma and a space which is not pretty. Add the comma and whitespace only when a previous feature has already been shown.

cmd: ufetch: show net feature when NET_LWIP is selected

2026-05-18T09:04:14Z

We've had a new lwIP networking stack for a couple of years already, so let's show there is a "net" feature if it's selected. Since NET_LEGACY || NET_LWIP is the same as NET, let's check on NET.

rename NET to NET_LEGACY

2026-04-27T17:26:40Z

Highlight that NET really is the legacy networking stack by renaming the option to NET_LEGACY. This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL. The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is using the legacy networking app so this seems fine to do. This also has the benefit of removing potential confusion on NET being a specific networking stack instead of "any" network stack.

cmd: ufetch: use 3-bit colour ANSI codes

2025-02-26T13:48:27Z

Currently, the 8-bit escapes are being used, which aren't supported by vidconsole_escape_char. Since the current usage maps directly to the 3-bit equivalents anyway, let's use those instead. With this change, the fetch output looks as fetching in the vidconsole as it does over serial! Signed-off-by: Sam Day Tested-by: Alexey Minnekhanov Tested-by: Ferass El Hafidi

cmd: ufetch: Show CPU architecture under "CPU"

2025-01-22T15:43:54Z

When looking at ufetch output it isn't immediately obvious which CPU architecture the presented board has. This patch therefore adds the CPU architecture string (for example "powerpc") to the "CPU:" line. The new format is: CPU: powerpc (1 cores, 1 in use) Signed-off-by: J.

cmd: ufetch: Fix type mismatch on 32-bit

2025-01-22T15:43:54Z

On 32-bit architectures, LAST_LINE (_LAST_LINE - 1UL) is 64 bits long, but size_t (from ARRAY_SIZE(...)) is 32 bits. This results in a warning because the max() macro expects the same type on both sides: cmd/ufetch.c: In function ‘do_ufetch’: include/linux/kernel.h:179:24: warning: comparison of distinct pointer types lacks a cast [-Wcompare-distinct-pointer-types] 179 | (void) (&_max1 == &_max2); \ | ^~ cmd/ufetch.c:92:25: note: in expansion of macro ‘max’ 92 | int num_lines = max(LAST_LINE + 1, ARRAY_SIZE(logo_lines)); | ^~~ Fix this by casting LAST_LINE to size_t.

cmd: add a fetch utility

2024-11-29T20:41:47Z

Add a small utility for displaying some information about U-Boot and the hardware it's running on in a similar fashion to the popular neofetch tool for Linux [1]. While the output is meant to be useful, it should also be pleasing to look at and perhaps entertaining. The ufetch command aims to bring this to U-Boot, featuring a colorful ASCII art version of the U-Boot logo.
