This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

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.
