[U-Boot] [PATCH 01/11] imx: ventana: set dynamic env var for flash layout

[Tim Harvey]

NAND devices have differing layouts with respect to page size and pages per
block. These parameters affect the parameters that need to be passed to
mkfs.ubifs and ubinize used to create UBI images. The various NAND chips
supported by Gateworks Ventana fall into two different layouts which we
refer to as 'normal' and 'large'. This layout is useful when referencing
ubi files to download and flash so we create a dynamic env variable for it.

[U-Boot] [PATCH 02/11] imx: ventana: added cputype env var

[Tim Harvey]

There are many similarities between the IMX6QUAD/IMX6DUAL and there are
many similarities between the IMX6SOLO/IMX6DUALITE. Add a 'soctype' env
variable that tells you which type you have.

[U-Boot] [PATCH 03/11] imx: ventana: remove caam disable per eeprom bit

[Tim Harvey]

During manufacturing this bit is not getting enabled when it should be, so
we will ignore it.

[U-Boot] [PATCH 04/11] imx: ventana: add appropriate delay following GSC i2c write

[Tim Harvey]

The Gateworks System Controller EEPROM config is flash based. Add a delay
following writes to avoid errors on back-to-back writes.

[U-Boot] [PATCH 05/11] imx: ventana: add econfig command

[Tim Harvey]

The Gateworks Ventana EEPROM contains a set of configuration bits that
affect the removal of device-tree nodes that support peripherals that do not
exist on sub-loaded boards. This patch adds:
 - a structure to define a config bit name, dt node alias, bit position
 - an array of supported configuration items
 - an econfig command to get/set/list configuration bits
 - use of the array when adjusting the FDT prior to boot

[U-Boot] [PATCH 08/11] imx: ventana: configure i2c_dis# pin properly for gw53xx

[Tim Harvey]

The i2c_dis# pinmux/padconf was missing for the GW53xx (this feature was
added to the GW53xx on revB PCB's). Additionally, remove the duplicate
config for GW54xx.

So you have soc=mx6 and soctype=<value of cputype>, if CONFIG_SYS_SOC is
set.

Is it important to have both or you can simply redefine the variable "soc" ?

Hi Stefano,

Yes, I do feel its important, although the name and where its set is debatable.

There are enough similarities between an IMX6DUAL/IMX6QUAD vs an
IMX6SOLO/IMX6DUALLITE making it such that if your board supports all 4
CPU's, you would usually have just two device-tree files:
imx6q-<foo>.dtb (supporting both the QUAD and the DUAL soc variants)
and imx6dl-<foo>.dtb (supporting both the DUALLITE and SOLO soc
variants).

Regards,

Tim

I agree on that, my only concern if the variable "soc" set to "mx6" has
still a meaning. When "soctype" is set to "imx6dl" (or whatever), "soc"
loses its meaning. Then it could be possible to set "soc" to the value
of cputype instead of adding a new one. What do you think ?=

Anyway, this is *not* a blocking point on my side. I will apply the
patch as it is if you think it is better for your board.

Best regards,
Stefano Babic
