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> |

Freescale MPC8610HPCD board =========================== Building U-Boot --------------- $ make MPC8610HPCD_config Configuring for MPC8610HPCD board... $ make Flashing U-Boot --------------- The flash is 128M starting at 0xF800_0000. The alternate image is at 0xFBF0_0000 The boot image is at 0xFFF0_0000. To Flash U-Boot into the booting bank: tftp 1000000 u-boot.bin protect off all erase fff00000 +$filesize cp.b 1000000 fff00000 $filesize To Flash U-Boot into the alternate bank tftp 1000000 u-boot.bin erase fbf00000 +$filesize cp.b 1000000 fbf00000 $filesize pixis_reset command ------------------- A new command, "pixis_reset", is introduced to reset mpc8610hpcd board using the FPGA sequencer. When the board restarts, it has the option of using either the current or alternate flash bank as the boot image, with or without the watchdog timer enabled, and finally with or without frequency changes. Usage is; pixis_reset pixis_reset altbank pixis_reset altbank wd pixis_reset altbank cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio> pixis_reset cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio> Examples; /* reset to current bank, like "reset" command */ pixis_reset /* reset board but use the to alternate flash bank */ pixis_reset altbank /* reset board, use alternate flash bank with watchdog timer enabled*/ pixis_reset altbank wd /* reset board to alternate bank with frequency changed. * 40 is SYSCLK, 2.5 is COREPLL ratio, 10 is MPXPLL ratio */ pixis-reset altbank cf 40 2.5 10 DIP Switch Settings ------------------- To manually switch the flash banks using the DIP switch settings, toggle both SW6:1 and SW6:2.
