9 years agolcd: split splash code into its own function

lcd: split splash code into its own function

lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.

Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
  lcd_clear() (which is arguably not the correct name for housing such
  code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
  lcd_clear() too.

mx53loco: Fix boot hang during reboot stress test

Currently by running the following test:

=> setenv bootcmd reset
=> save
=> reset

, we observe a hang after approximately 20-30 minutes of stress reboot test.

Investigation of this issue revealed that when a single DDR chip select is used,
the hang does not happen. It only happens when the two chip selects are active.

MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence":

"The controller must keep the memory lines quiet (except for CK) for the ZQ
calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256
for other ZQCL and 64 for ZQCS)."

According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL:

"Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines.
Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)"

So make sure to activate one chip select at time (CS0 first and then CS1 later),
so that the required JEDEC delay is respected for each chip select.

With this change applied the board has gone through three days of reboot stress
test without any hang.

Alexey Brodkin [Tue, 3 Feb 2015 10:58:20 +0000 (13:58 +0300)]
arc: build libgcc in U-Boot

This way we may have very limited set of functions implemented so we
save some space.

Also it allows us to build U-Boot for any ARC core with the same one
toolchain because we don't rely on pre-built libgcc.

For example:
 * we may use little-endian toolchain but build U-Boot for ether
endianess
 * we may use non-multilibbed uClibc toolchain but build U-Boot for
whatever ARC CPU flavour that current GCC supports

Private libgcc built from generic C implementation contributes only 144
bytes to .text section so we don't see significant degradation of size:
--->8---
$ arc-linux-size u-boot.libgcc-prebuilt
   text    data     bss     dec     hex filename
 222217   24912  214820  461949   70c7d u-boot.libgcc-prebuilt

 222361   24912  214820  462093   70d0d u-boot.libgcc-private
--->8---

Also I don't notice visible performance degradation compared to
pre-built libgcc (where at least "*div*" functions are had-written in
assembly) on typical operations of downloading 10Mb uImage over TFTP and

for booting can be built from mainline U-Boot. Without any additional
external inclusion. Hopefully other MVEBU SoC's will follow here.

Support for some SoC's has been removed in this version. This is:

MV_MSYS:
The code referred to by the MV_MSYS define is currently unused. And its

MV88F66XX (ALP):
The code referred to by the MV88F66XX define is currently unused. And its
not really planned to support this in mainline. So lets remove it to

MV88F78X60_Z1:

Z1 revision of the AXP is not supported in mainline anymore.
So lets remove it to make the code clearer and increase the readability.

Remove support for Z1 & A0 AXP revisions (steppings). The current stepping
is B0 and this is the only one that is actively supported in this code
version.

Tested on AXP using a SPD DIMM setup on the Marvell DB-MV784MP-GP board and
on a custom fixed DDR configuration board (maxbcm).

Note:
This code has undergone many hours of coding-style cleanup and refactoring.
It still is not checkpatch clean though, I'm afraid. As the factoring of the

unstable image when active low v or hsync is used.

The problem seems to be specific to the OLinuxIno A13 (normal & micro)
boards. I've just looked up the schematics and they use an opendrain driver
for the vga sync lines, and with sync pulses it is the logical high->low
edge of the pulse which counts for the timing, which with an active low
sync is being driven by the pull-up, and that simply seems to not drive
it hard enough to get a stable image.

So force v and hsync active high on these boards. independent of what the
modeline says. This fixes the unstable image.
