12 years agoOMAP4: Set fdt_high for OMAP4 devices to enable booting with Device Tree
Jon Hunter [Tue, 1 May 2012 10:05:08 +0000 (10:05 +0000)]
OMAP4: Set fdt_high for OMAP4 devices to enable booting with Device Tree

For OMAP4 boards, such as the panda-es, that have 1GB of memory the linux
kernel fails to locate the device tree blob on boot. The reason being is that
u-boot is copying the DT blob to the upper part of RAM when booting the kernel
and the kernel is unable to access the blob. By setting the fdt_high variable
to either 0xffffffff (to prevent the copy) or 0xac000000 (704MB boundary
of memory for OMAP4) the kernel is able to locate the DT blob and boot.

Based upon following patch by Dirk Behme set the fdt_high variable to allow
booting with device tree on OMAP4 boards.

Based on commit cf073e49bc3502be1b48a0e3faf0cde9edbb89db for beagleboard

Using the new env import command it is possible to use plain text files instead
of script-images. Plain text files are much easier to handle.

E.g. If your boot.scr contains the following:
 -----------------------------------
setenv dvimode 1024x768-16@60
run loaduimage
run mmcboot
-----------------------------------
you could create a file named uEnv.txt and use that instead of boot.scr:
 -----------------------------------
dvimode=1024x768-16@60
uenvcmd=run loaduimage; run mmcboot
-----------------------------------
The variable uenvcmd (if existent) will be executed (using run) after uEnv.txt
was loaded. If uenvcmd doesn't exist the default boot sequence will be started,
therefore you could just use
-----------------------------------
dvimode=1024x768-16@60
-----------------------------------
as uEnv.txt because loaduimage and mmcboot is part of the default boot sequence

Support for the Ctrl modifier is provided. The left and right ctrl keys are

is also used to decode (row, column) key positions into key codes.

picked up when the keyboard driver is initialized.

i.MX28: Add delay after CPU bypass is cleared

This solves issues when larger amount of DRAM is used, like 256MB.
Behave the same in case of CPU bypass as we do in case of EMI
bypass, but wait 15 ms. We need to wait until the clock domain
stabilizes.

This issue seemed to have been caused by not waiting after frobbing
with the CPU bypass, it was unrelated to memory, but had a direct
impact, causing trouble. This was yet another X-File of the
imx-bootlets, sigh. The conclusion is, trying a semi-random delay
(there is delay after the EMI bypass change), the issue is fixed.

Another possible explanation is that we do not do the "simple memory
test" FSL does in their imx-bootlets (1000 R/W cycles to/from piece of
the memory, while also outputing something on the serial port). This
might have caused the similar delay in the imx-bootlets and therefore
they didn't need to add this explicitly.

For now, this seems good fix enough, but to me, whole that memory
init code in imx-bootlets is completely flunked and it'd need deeper
investigation.

This reverts commit 69d26d09de1cb93e0a09ca71d9f0d41a66f0756a.

Apparently, this commit got mainline only because of out-of-tree
port and causes breakage on board that is mainline. Revert.

Reason:
* The OOT board has 512MB of DRAM, enabling this additional address
  line enabled it to work fine with 512MB of RAM.
* Every mainline port has max. 256MB of DRAM, therefore this revert
  has no impact on any mainline port
* Though this caused a problem with new M28 board with 256MB of DRAM
  where the chips are wired differently. The patch-to-be-reverted
  caused the DRAM to behave like this:

  [128MB chunk #1][128MB chunk #1 again][128MB chunk #2][128MB chunk #2 again]

Therefore to retain the current one-memory-init-rules-them-all situation,
revert this patch until another board emerges and will actually be pushed

There are two types of mx53loco boards: initial boards were built with a Dialog
DA9053 PMIC and more recent version is based on a Freescale MC34708 PMIC.

Add DA9053 PMIC support and adjust the required voltages and clocks for running
the CPU at 1GHz.

Tested on both versions of mx53loco boards.

In the case of a MC34708-based board the CPU operating voltage remains at 800MHz.
