Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>

fs: ext4: skip journal state if fs has metadata_csum 2020-04-27T18:55:29+00:00 Arnaud Ferraris arnaud.ferraris@collabora.com 2020-04-22T10:43:44+00:00 7683b11098ded5087138d84e2e85078335a0cb72 As u-boot doesn't support the metadata_csum feature, writing to a filesystem with this feature enabled will fail, as expected. However, during the process, a journal state check is performed, which could result in: - a fs recovery if the fs wasn't umounted properly - the fs being marked dirty Both these cases result in a superblock change, leading to a mismatch between the superblock checksum and its contents. Therefore, Linux will consider the filesystem heavily corrupted and will require e2fsck to be run manually to boot. By bypassing the journal state check, this patch ensures the superblock won't be corrupted if the filesystem has metadata_csum feature enabled.

dm: core: Create a new header file for 'compat' features 2020-02-06T02:33:46+00:00 Simon Glass sjg@chromium.org 2020-02-03T14:36:16+00:00 336d4615f8fa774557d14f9b3245daa9e5fe3dbc At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.
