Steffen Trumtrar 26121ef51d ARM: zynq: add zynq fsbl checksum script
The bootrom only reads an image if the correct checksum is present in the
header. The calculation is pretty simple:
sum over all words from 0x20 to 0x44
Two of this words are the image length. That is why the checksum can not be
calculated until barebox_image_size is known.
The easiest solution is a program that has to be run after make.

Steffen Trumtrar 097513b8f8 ARM: zynq: add clk support for zynq7000
This adds support for the clocktree on zynq7000 SoCs.
The patch is based on clocks.c from the larger patch
	ARM: zynq: add suppport for Zynq 7000 SoC
by Josh Cartwright.

The driver in that patch is converted to a platform_driver and code to
enable plls was added.

Sascha Hauer f1e1dc306d ARM i.MX ESDCTL: Fix default enabled esdctl v2 controller
On some i.MX SoCs the SDRAM controller has chipselect 2 enabled
by reset default. This confuses our SDRAM size detection. We
already have a fix for this in place. This patch adds the fix
for i.MX35 which needs it aswell. Also since we now detect the
SDRAM size in the SoC specific entry functions we have to apply
the fixup there, too.

Sascha Hauer a81ec0225f ARM: Add relocatable binary support
For making the same binary executable on different SoCs which have
different DRAM addresses we have to be independent of the compile
time link address.

This patch adds relocatable binary support for the ARM architecture.
With this two new functions are available. relocate_to_current_adr
will fixup the binary to continue executing from the current position.
relocate_to_adr will copy the binary to a given address, fixup the
binary and continue executing from there.

For the PBL and the real image relocatable support can be enabled
independently. This is done to (hopefully) better cope with setups
where the PBL runs from SRAM or ROM and the real binary does not.

Sascha Hauer 74d44e7b2a ARM: provide accessor functions for linker variables
With relocatable binaries the linker is not able to supply absolute
addresses. These only get available when the relocation function is
being run. Since for early initialization we need some variables
before relocation, we supply them relatively to some known address
in the binary. This means that the variables have to be converted
to absolute addresses during runtime.

This patch adds a C macro and an assembly macro to calculate the
variables during runtime.

Sascha Hauer 457c038f83 ARM i.MX35: Let MAX clk be in run-mode-on
The reset value for the MAX clk gate is 0b10, that is it is turned
on in CPU run mode and off in stop mode. Configure it that way during
startup.

The 0b11 value previously in this field causes some nasty behaviour in
the Linux kernel:

- The i.MX35 has two bits per clock gate which are decoded as follows:
  0b00 -> clock off
  0b01 -> clock is on in run mode, off in wait/doze
  0b10 -> clock is on in run/wait mode, off in doze
  0b11 -> clock is always on

The MAX clock is needed by the SoC, yet unused in the Kernel, so the
common clock framework will disable it during late init time. It will
only disable clocks though which it detects as being on. This detection
is made depending on the lower bit of the gate. So with the value of
0b11 the clock framework will detect the clock as turned on, yet unused,
hence it will turn it off and the system locks up.
With the value of 0b10 instead, the clock framework will detect the
clock as being disabled and will not try to turn it off, so the
system works.

The real bug is in the Linux clock framework. However, the value 0f 0b10
seems to be a sane default value, so restore it. This lets Linux work
again and gives time to fix the bug in Linux.

We cannot jump to SDRAM unconditionally in imx*_barebox_boot_nand_external.
When we really boot from NOR flash the binary is not yet copied to SDRAM.
Instead, let the return value of imx_barebox_boot_nand_external() indicate
whether we really boot from NAND and only jump to SDRAM in this case.
Otherwise just continue to the normal SoC specific entry.

Ivan Djelic 3fe6f23b76 arm: fix memset-related crashes caused by recent GCC (4.7.2) optimizations
Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on
assumptions about the implementation of memset and similar functions.
The current ARM optimized memset code does not return the value of
its first argument, as is usually expected from standard implementations.

For instance in the following function:

void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter)
{
	memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter));
	waiter->magic = waiter;
	INIT_LIST_HEAD(&waiter->list);
}

compiled as:

800554d0 <debug_mutex_lock_common>:
800554d0:       e92d4008        push    {r3, lr}
800554d4:       e1a00001        mov     r0, r1
800554d8:       e3a02010        mov     r2, #16 ; 0x10
800554dc:       e3a01011        mov     r1, #17 ; 0x11
800554e0:       eb04426e        bl      80165ea0 <memset>
800554e4:       e1a03000        mov     r3, r0
800554e8:       e583000c        str     r0, [r3, #12]
800554ec:       e5830000        str     r0, [r3]
800554f0:       e5830004        str     r0, [r3, #4]
800554f4:       e8bd8008        pop     {r3, pc}

GCC assumes memset returns the value of pointer 'waiter' in register r0; causing
register/memory corruptions.

This patch fixes the return value of the assembly version of memset.
Could you please review, or suggest better alternatives ?

Thanks,

(this is a shorter and (hopefully) clearer repost of
http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/144916.html)

The patch adds a 'mov' instruction and merges an additional load+store into
existing load/store instructions.
For ease of review, here is a breakdown of the patch into 4 simple steps:

Step 1
======
Perform the following substitutions:
ip -> r8, then
r0 -> ip,
and insert 'mov ip, r0' as the first statement of the function.
At this point, we have a memset() implementation returning the proper result,
but corrupting r8 on some paths (the ones that were using ip).

Step 2
======
Make sure r8 is saved and restored when (! CALGN(1)+0) == 1:

save r8:
-       str     lr, [sp, #-4]!
+       stmfd   sp!, {r8, lr}

and restore r8 on both exit paths:
-       ldmeqfd sp!, {pc}               @ Now <64 bytes to go.
+       ldmeqfd sp!, {r8, pc}           @ Now <64 bytes to go.
(...)
        tst     r2, #16
        stmneia ip!, {r1, r3, r8, lr}
-       ldr     lr, [sp], #4
+       ldmfd   sp!, {r8, lr}

Step 3
======
Make sure r8 is saved and restored when (! CALGN(1)+0) == 0:

save r8:
-       stmfd   sp!, {r4-r7, lr}
+       stmfd   sp!, {r4-r8, lr}

and restore r8 on both exit paths:
        bgt     3b
-       ldmeqfd sp!, {r4-r7, pc}
+       ldmeqfd sp!, {r4-r8, pc}
(...)
        tst     r2, #16
        stmneia ip!, {r4-r7}
-       ldmfd   sp!, {r4-r7, lr}
+       ldmfd   sp!, {r4-r8, lr}

Step 4
======
Rewrite register list "r4-r7, r8" as "r4-r8".

Sascha Hauer e55f9d10b4 defenv2: move config-board out of /env/init
Having the board config file in /env/init has the problem that
the settings in /env/config are overwritten in the init sequence.

This moves the config-board files to /env/ and sources them explicitly
from /env/bin/init before sourcing /env/config

Steffen Trumtrar 2ccd4510bd ARM i.MX28: change default watchdog reset method
The default setting for the imx28 watchdog is to do a power-off reset. If the
SoC is only powered via battery, then the watchdog powers the chip down, though.
According to the datasheet it should still be possible to execute a proper POR
with battery power, but testing showed otherwise.
When the watchdog power-off reset is disabled, a software reset is executed
instead. This works with and without battery power.

if you use 1GiB of ram you can run the same barebox on Cortex-A15 or Cortex-A9
otherwise use vexpress_ca9_defconfig where the TEXT_BASE is at 0x63f00000

when we will add the relocation support this defconfig will be drop
