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> |

Board information ----------------- The evaluation board "pbab01" is thought to be used together with the SOM. More information on the board can be found on manufacturer's website: http://www.phytec.de/produkt/system-on-modules/phyflex-imx-6/ Building U-Boot ------------------------------- $ make pfla02_defconfig $ make This generates the artifacts SPL and u-boot.img. The SOM can boot from NAND or from SD-Card, having the SPI-NOR as second option. The dip switch "SW3" on the board let choose the boot device. SW3_1(on), SW3_2(on), SW3_3(off): Boot first from SD, then try SPI SW3_1(off), SW3_2(on), SW3_3(off): Boot from SPI
