2020-08-04net: tftp: Add client support for RFC 7440Ramon Fried
Add support for RFC 7440: "TFTP Windowsize Option". This optional feature allows the client and server to negotiate a window size of consecutive blocks to send as an alternative for replacing the single-block lockstep schema. windowsize can be defined statically during compilation by setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by setting an environment variable: "tftpwindowsize" If not defined, the windowsize is set to 1, meaning that it behaves as it was never defined. Choosing the appropriate windowsize depends on the specific network topology, underlying NIC. You should test various windowsize scenarios and see which best work for you. Setting a windowsize too big can actually decreases performance. Signed-off-by: Ramon Fried <rfried.dev@gmail.com> Reviewed-by: Marek Vasut <marex@denx.de>

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-07-07net: dm: Remove warning about EEPROM provided MAC addressAndre Przywara
Similar to patch 821fec0ceb3e ("net: remove scary warning about EEPROM provided MAC address") this removes the somewhat awkward "warning" on boards using DM_ETH: In many parts of the computing world having a unique MAC address sitting in some on-NIC storage is considered the normal case. If there is a properly provided MAC address (either from ROM or from DT), remove the warning to not scare the user unnecessarily.

2020-05-10net: Add eth phy generic driver for shared MDIOYe Li
For dual ethernet controllers, the HW design may connect ETH phys to one MDIO ports. So two different ethernet drivers have to share MDIO bus. Since two ethernet drivers are independent, we can't ensure their probe order. To resolve this problem, introduce an eth phy generic driver and uclass. After eth-uclass binds, we search the mdio node and binds the phy node with the eth-phy-generic driver. When one eth driver get its phy device, the parent of phy device will probe prior than phy device. So this ensure the eth driver ownes the MDIO bus will be probed before using its MDIO.

2019-12-09net: tftp: Fix too small block sizeAndre Przywara
Commit b618b3707633 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig") accidentally set the default *option* TFTP block size to 512 bytes, even though the comment in the code says that this is a terrible choice. Most boards didn't define the symbol before, so they got the default block size of 1468 bytes before, but now use 512 bytes, which is also the fallback. This leads to both abysmal performance and a lot of hashes printed on the screen (one character for every 5K), which is both annoying and slow over serial links. Set the default block size in Kconfig back to the value it had before. This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.
