* ehci: speed up initializationVincent Palatin2011-12-11-1/+1
| | | | | | | | | | According to EHCI specification v1.0, the controller should stabilize the power on a port at most 20 ms after the port power bit transition. So, we put this setting in the virtual descriptor corresponding field, (bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each controller initialization/enumeration.

* usb: align usb_endpoint_descriptor to 16-bit boundaryStefan Kristiansson2011-12-11-1/+1
| | | | | | | | | | | | | | | | | The usb_endpoint_descriptor struct is 7 bytes large and is defined as an array (ep_desc[USB_MAXENDPOINTS]) in the usb_interface struct in include/usb.h This fact will result in that every odd index in that array will start at an uneven address, this in turn makes accesses to u16 wMaxPacketSize unaligned. Such accesses are illegal on the OpenRISC architecture (as well as other architectures) and will render a bus error. Setting the aligned(2) attribute on usb_endpoint_descriptor will force wMaxPacketSize to a 16-bit boundary. Signed-off-by: Stefan Kristiansson <stefan.kristiansson@saunalahti.fi>

| * M28: Cleanup memsize.o OOT buildMarek Vasut2011-12-09-23/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current way memsize.c is built just made a symlink into the directory with SPL and then compiled it like any other file there. This was bad as that broke the out-of-tree build. The new way introduced in this patch uses the standard spl/Makefile methods (CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in common/ be built. Because common/Makefile says memsize.c is always built (SPL and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SOCs have do not start up with their 'main' CPU. The first U-Boot code may then be executed with a CPU which does not have a CP15, or not a useful one. Here we split the initialization of CP15 into a separate call, which can be performed later if required. Once the main CPU is running, you should call cpu_init_cp15() to perform this init as early as possible. Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not need to change, this CP15 init is still skipped in that case. The only impact for these boards is that the cpu_init_cp15() will be available even if it is never used on these boards.

| * tegra2: Simplify tegra_start() boot pathSimon Glass2011-12-09-25/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra2 boot path is more complicated than it needs to be. Since we want to move to building most of U-Boot with ARMv7 and only a small part with ARMv4T (for AVP) it should be as simple as possible. This makes tegra2_start() into a simple function which either does AVP init or A9 init depending on which core is running it. Both cores now following the same init path, beginning at _start, and the special Tegra2 boot path code is no longer required. Only two files need to be built for ARMv4T, and this is handled in the Tegra2 CPU Makefile. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
| * tegra2: Add arch_cpu_init() to fire up Cortex-A9Simon Glass2011-12-09-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | We want to move away from a special Tegra2 start-up, and just use arch_cpu_init() instead. However, if we run board_init_f() from boot we need to build it for ARMv4T, since the Tegra's AVP start-up CPU does not support ARMv7. The effect of this is to do the AVP init earlier, and in arch_cpu_init(), rather that board_early_init_f().
