u-boot.git/common/spl, branch v2013.01.01 Unnamed repository; edit this file 'description' to name the repository. SPL: Port SPL framework to powerpc 2012-12-05T16:30:22+00:00 Stefan Roese sr@denx.de 2012-08-23T06:34:21+00:00 ea8256f072ccc04c83fa10030673cdd4cd01cbd9 This patch enables the SPL framework to be used on powerpc platforms and not only ARM. timer_init() does not exist on PPC systems. The timer (decrementer) is initialized and enabled in interrupt_init() here. And currently interrupt_init() is called after relocation to SDRAM. Since the only powerpc SPL implementation (a3m071) doesn't need a timer, let's remove this timer_init() call for PPC systems. Signed-off-by: Stefan Roese <sr@denx.de>

SPL: make jump_to_image_no_args a weak symbol 2012-10-29T16:07:05+00:00 Allen Martin amartin@nvidia.com 2012-10-19T21:08:22+00:00 a759f1e0db7be05ab562e060cf024af262920426 Change jump_to_image_no_args() to a weak symbol to allow override by SoC specific code. This is required by tegra because the SPL runs on a different CPU from the image it is loading, so tegra specific initialization is required to start the host CPU. Pass in spl_image as a parameter for the same reason.

OMAP: networking support for SPL 2012-10-01T17:02:14+00:00 Ilya Yanok ilya.yanok@cogentembedded.com 2012-09-18T00:22:50+00:00 7ac2fe2da21d292aeaf3af74e5c80de9ce9dab56 This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.

SPL: Rework how we inform about un-headered images 2012-09-27T18:20:28+00:00 Tom Rini trini@ti.com 2012-08-27T21:58:28+00:00 4212098181ac91e14374c1207b1e98595f1cc717 First, remove the puts from the case where we don't have an mkimage header as this is somewhat common and intentional for no-arg target images. Second, rework the final switch statement in board_init_r to, in the case of !CONFIG_SPL_OS_BOOT be only about doing debug prints about if we know what the magic is or not (the CONFIG_SPL_OS_BOOT case is unchanged). Then we call jump_to_image_no_args(). This gives us the same behavior as before but with slightly smaller code. Signed-off-by: Tom Rini <trini@ti.com>
