To: u-boot
add support for the imx6 based aristainetos board.
- changes for v2:
- added comments from Jagan Teki and Stefano Babic
- remove patch http://patchwork.ozlabs.org/patch/353324/
- new patches in v2
imx6: add gpr2 usb_otg_id iomux select control define
(as patch http://patchwork.ozlabs.org/patch/353324/
is removed in v2)
i.MX6: define struct pwm_regs and PWMCR_* defines
(as splash screen support added for this board)
- changes for v3
- remove patch
http://patchwork.ozlabs.org/patch/369530/
from this patchserie, as Jagannadha Sutradharudu Teki applied it
to u-boot-spi/master
- new patch:
spi: add config option to enable the WP pin function on st micron flashes
as Stefano Babic suggested to move this to common code
- new patch:
pwm, imx6: add support for pwm modul on imx6
as Stefano Babic suggested to move this to common code
Cc: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
Cc: Stefano Babic <sbabic@denx.de>
Heiko Schocher (6):
imx6: add gpr2 usb_otg_id iomux select control define
i.MX6: define struct pwm_regs and PWMCR_* defines
pwm, imx6: add support for pwm modul on imx6
i.MX6: add enable_spi_clk()

- changes for v2:
- change MUX_PAD_CTRL value for MX6_PAD_GPIO_16__ENET_REF_CLK
- set cs1 from ecspi4 to high
- add splash screen support
- add comment from Stefano babic:
- remove mxc_iomux_set_gpr_register instead use setbits_le32
remove patch http://patchwork.ozlabs.org/patch/353324/
from this patchserie, as no longer needed
- use for loop for calling enable_spi_clk()
- simplify board_mmc_getcd()
- simplify board_mmc_init()
- remove board_phy_config()
- remove setup_fec() and work code into
board_eth_init()
- use define for i2c slave address
- remove udelay in board_ehci_hcd_init()
- remove CONFIG_SPL_BUILD, as this board does not use
CONFIG_SPL_BUILD
- changes for v3:
- add comment from Stefano Babic:
- simplify setup_iomux_uart()
- remove enable_spi()
- remove enable wp pin for the st micron flash from board code
to spi driver. Enable this new config option only in board
config file
- use common functions from pwm modul

I am asking myself the reason to have this kind of #ifdef. I understand
that we use to bypass for debugging purpose some part of code, but this
does not mean that this pseudo-debug code should flow to mainline. Do
you plan to make CONFIG_CMD_FUSE configurable ? If not, what about to
remove the #ifdef ?

Same here. If we know that the board will need CONFIG_CMD_SF, the #ifdef
is useless

Yes, that would be good. Could you add this info, when applying
it to u-boot.imx? (I think you pick up the complete patchserie, or?)
If I have to post a v4 patchserie, I add this info to the commit
message.

Thanks!

Is this really GPL-2.0+ ? The Linux driver is definitely GPL-2.0
only!

Not should - must!
Exact reference including commit ID is mandatory!
