2012-11-19mx5: Mark lowlevel_init board-specific codeBenoît Thébaudeau
The mx5 lowlevel_init.S contains board-specific code based on the reference design. Let's keep it since it avoids creating new lowlevel_init files and it may be used by many boards. But add a config to make it optional in order not to cause issues on boards not following this part of the reference design.

2012-11-04include/linux/byteorder: import latest endian definitions from linuxKim Phillips
u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives. Import the kernel's latest definitions, and enable them by including compiler.h and types.h. They come with 'const' added for some swab functions, so fix those up, too: include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default] Also, note: u-boot's historic __BYTE_ORDER definition has been preserved (for the time being at least). We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)).

2012-10-29ARM: enhance u-boot.lds to detect over-sized SPLStephen Warren
Add an ASSERT() to u-boot.lds to detect an SPL that doesn't fit within SPL_TEXT_BASE..SPL_MAX_SIZE. Different .lds files implement this check in two possible ways: 1) An ASSERT() like this 2) Defining a MEMORY region of size SPL_MAX_SIZE, and re-directing all linker output into that region. Since u-boot.lds is used for both SPL and main U-Boot, this would entail only sometimes defining a MEMORY region, and only sometimes performing that redirection, and hence option (1) was deemed much simpler, and hence implemented. Note that this causes build failures at least for NVIDIA Tegra Seaboard and Ventana. However, these are legitimate; the SPL doesn't fit within the required space, and this does cause runtime issues.

2012-10-26ARM: fix u-boot.lds for -ffunction-sections/-fdata-sectionsStephen Warren
When -ffunction-sections or -fdata-section are used, symbols are placed into sections such as .data.eserial1_device and .bss.serial_current. Update the linker script to explicitly include these. Without this change (at least with my gcc-4.5.3 built using crosstool-ng), I see that the sections do end up being included, but __bss_end__ gets set to the same value as __bss_start.

2012-10-26MX35: add support for woodburn boardStefano Babic
The woodburn board is based on the MX35 SOC. Support for both external (NOR) and internal (SD Card) boot mode are added. It uses the generic SPL framework to implement the internal boot mode. The following peripherals are supported: - Ethernet (FEC) - SD Card - NAND (512 MB) - NOR Flash In the internal boot mode, a simple imximage header is generated to set the address in internal RAM where the SOC must copy the SPL code. The initial setup is then demanded to the SPL itself. Signed-off-by: Stefano Babic <sbabic@denx.de>

2012-10-25am335x: Enable RTC 32K OSC clockVaibhav Hiremath
In order to support low power state, you must source kernel system timers to persistent clock, available across suspend/resume. In case of AM335x device, the only source we have is, RTC32K, available in wakeup/always-on domain. Having said that, during validation it has been observed that, RTC clock need couple of seconds delay to stabilize the RTC OSC clock; and such a huge delay is not acceptable in kernel especially during early init and also it will impact quick/fast boot use-cases. So, RTC32k OSC enable dependency has been shifted to SPL/first-bootloader. Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tom Rini <trini@ti.com>
