Martin Roth ba9d51ee38 documentation: Add small coreboot logo in PNG format
The doxygen output looks better with the coreboot logo,
so I'm adding the 2k png from the wiki to the documentation
directory to use in the doxygen build.

Vadim Bendebury 11aaf1f42a ipq8064: Add work around for slow timer clock
Libpayload libc requires timer clock frequency to be at least 1MHz.
Ipq8064 code presently provides a single option of 32kHz. Pretend to

This is a hack which will be reverted as soon as the SOC is configured
to supply a faster running clock.

Vadim Bendebury 24a53dddb9 ipq806x: clean up UART driver tx_byte function
The driver as it was copied from u-boot provided a function to
transmit multiple characters in one invocation. This feature was not
ported to coreboot, there is no need to maintain the complexity when
only one character at a time is transmitted. It is also very desirable
to get rid of a 1024 byte array allocated on the stack.

The array was necessary to allow to convert multiple newline
characters in the transmit data flow into two character sequences
CRLF. Now just a single word is enough to keep one or two characters
to transmit.

[EDIT km: newline translation is now part of printk]

BUG=chrome-os-partner:27784
TEST=verified that coreboot with the new code prints generates console
     output.

In https://chromium-review.googlesource.com/181272 the payload->type has been

Vadim Bendebury 0e2d9b63d7 storm: ipq8064: enable CBFS SPI wrapper
This change forces storm platform to use the common CBFS SPI wrapper,
which makes the SOC specific CBFS code unnecessary and requires
including SPI controller support in all coreboot stages.

BUG=chrome-os-partner:27784
TEST=manual
  . with this change and the rest of the patches coreboot on AP148
    comes up all the way to attempting to boot the payload (reading
    earlier stages from the SPI flash along the way).

This service is required by various coreboot code modules. It looks

running counter (it is used in u-boot for us timer as well). Let's use
this for now.

Julius Werner 989e12bb63 arm: Fix stored PC value when handling exceptions
ARM processors save the PC value in the Link Register when they handle
and exception, but they store it with an added offset (depending on the
exception type). In order to make crashes easier to read and correctly
support more complicated handlers in libpayload, this patch adjusts the
saved PC value on exception entry to correct for that offset.

(Note: The value that we now store is what ARM calls the "preferred
return address". For most exceptions this is the faulting instruction,
but for software interrupts (SWI) it is the instruction after that. This
is the way most programs like GDB expect the stored PC address to work,
so let's leave it at that.)

Numbers taken from the Architecture Reference Manual at the end of
section B1.8.3.

BRANCH=none
BUG=chrome-os-partner:18390
TEST=Provoked a data abort and an undefined instruction in both coreboot
and depthcharge, confirmed that the PC address was spot on.
