[U-Boot] [PATCH 1/3] mx53: Change IPU_CTRL_BASE_ADDR definition

[U-Boot] [PATCH 1/3] mx53: Change IPU_CTRL_BASE_ADDR definition

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

The original definition of IPU_CTRL_BASE_ADDR does match the value stated
in the MX53 Reference Manual.

However, if using such value the IPU driver hangs when trying to access the IPU registers.

Looking for this definition in Freescale U-boot version shows that it is set as 0.

Set it as 0 here as well, so that we can have a working IPU driver for mx53.

[U-Boot] [PATCH 2/3] mx5: Rename mx51_fb_init()

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

The ipuv3 driver is currently only used on mx51, but it can be extended to work
on mx53 and mx6 as well.

Rename mx51_fb_init(), so that it can be used by other SoCs.

[U-Boot] [PATCH 3/3] mx53loco: Add LCD support

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

Add support for CLAA07LC0ACW LCD that connects to the mx53loco board.

Configure the board to show the Linux logo on the LCD.

Also increase the size of CONFIG_SYS_MALLOC_LEN variable to take into account 
the framebuffer usage.

Apart of the fact that it works, this chane appears really strange to
me. Maybe now it is not writing anymore in ipu, and the default values
are ok for mx53. It seems more a MX53 related issu in IPU3 driver, and
this change maybe hides the real problem. Do you have any additional
information to make this modification against the official Freescale's
reference manual ?

Regards,
Stefano

I investigated this and I understand it better now.

I am working on a solution that will be flexible to handle mx51/mx53/mx6.
