arm: Allow cleanup_before_linux() without disabling caches

2015-06-11T01:26:54+00:00

This function is used before jumping to U-Boot, but in that case we don't
always want to disable caches.

meminfo cmd: Enable printing >=4GiB SDRAM sizes

2015-05-28T12:18:21+00:00

gd->ram_size is stored as phys_size_t type which can be bigger than an
unsigned long on some architectures.  When using unsigned long type,
SDRAM of 4GiB or larger will not print the correct size, but using
phys_size_t will.

Move display_options functions to their own header

2015-04-30T03:02:33+00:00

Before adding one more function, create a separate header to help reduce
the size of common.h. Add the missing function comments and tidy up.

gunzip: add gzwrite routine for extracting compresed images to block device

2015-04-22T16:14:55+00:00

Initial filesystem images are generally highly compressible.

Add a routine gzwrite that allows gzip-compressed images to be
written to block devices.

powerpc/mpc85xx: Remove some dead code

2015-04-20T17:15:29+00:00

U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code.  It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.

The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).

Also remove a few other small unused functions.

net: cosmetic: Change IPaddr_t to struct in_addr

2015-04-18T17:11:32+00:00

This patch is simply clean-up to make the IPv4 type that is used match
what Linux uses. It also attempts to move all variables that are IP
addresses use good naming instead of CamelCase. No functional change.

common: Make sure arch-specific map_sysmem() is defined

2015-04-18T17:11:09+00:00

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

dm: Add a new CPU init function which can use driver model

2015-04-17T01:27:41+00:00

Since driver model is set up after arch_cpu_init(), that function cannot
use drivers. Add a new arch_cpu_init_dm() function which is called
immediately after driver model is ready, and can reference devices.

This can be used to probe essential devices for the CPU.

powerpc/mpc85xx: Add DSP side awareness for Freescale Heterogeneous SoCs

2015-03-04T18:15:29+00:00

The code provides framework for heterogeneous multicore chips based on StarCore
and Power Architecture which are chasis-2 compliant, like B4860 and B4420

It will make u-boot recognize all non-ppc cores and peripherals like
SC3900/DSP CPUs, MAPLE, CPRI and print their configuration in u-boot logs.
Example boot logs of B4860QDS:
