* usb: hub: Add 3.0 hub port status mask of 2.0 hubBin Meng2017-07-281-1/+6

* usb: hub: Change USB hub descriptor to match USB 3.0 hubsBin Meng2017-07-281-4/+14
| | | | | | | | | | | | USB 3.0 hubs have a slightly different hub descriptor than USB 2.0 hubs, with a fixed (rather than variable length) size. Change the host controller drivers that access those last two fields (DeviceRemovable and PortPowerCtrlMask) to use the union.

* usb: hub: Send correct wValue to get hub descriptor of a USB 3.0 hubBin Meng2017-07-281-0/+1
| | | | | | | | | | | | | | | Testing a USB 3.0 hub by connecting it to the xHCI port on Intel MinnowMax, when issuing 'get hub descriptor' to the hub, xHCI reports a transfer event TRB with a completion code 6 which means 'Stall Error'. In fact super speed USB hub descriptor type is 0x2a, not 0x29. Sending correct SETUP packet to the hub makes it not stall anymore.

* dm: core: add ofnode_count_phandle_with_args()Patrice Chotard2017-07-283-0/+60
| | | | | | | | | | | | | | | | | | | | This function is usefull to get phandle number contained in a property list. For example, this allows to allocate the right amount of memory to keep clock's reference contained into the "clocks" property. To implement it, either of_count_phandle_with_args() or fdtdec_parse_phandle_with_args() are used respectively for live tree and flat tree. By passing index = -1, these 2 functions returns the number of phandle contained into the property list. Add also the dev_count_phandle_with_args() based on ofnode_count_phandle_with_args() Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

* | configs: ti: armv7: Fixes bug in fit_loadaddr for ramfs bootMadan Srinivas2017-07-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The load address of ramdisk, rdaddr is 0x88080000 and fit_loadaddr is defined as 0x88000000. This leaves only 512Kbytes for the fit image. When the FIT images are larger than this, it will overwite the ramdisk and cause the boot to fail. For eg, The K2 HS fit images are a few MB and end up overwriting the ramdsk. This patch moves the fit_loadaddr to 0x87000000, leaving a 16MB window for the fit image. This memory can be reclaimed once the kernel starts running. Signed-off-by: Madan Srinivas <madans@ti.com>

However not all the choices are available in Kconfig yet so we cannot use that. It would lead to more than one option being set. In addition, one purpose of this series is to allow the environment to be stored in more than one place. So the existing choice is converted to a normal config allowing each option to be set independently. There are not many opportunities for Kconfig updates to reduce the size of this patch. This was tested with ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC And then manual updates. This is because for CHAIN_OF_TRUST boards they can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic now.

In addition, as the Makefile compiles cmd/reginfo.c only when CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD definition inside a #ifdef CONFIG_CMD_REGINFO Lets all remove the #ifdefs around the U_BOOT_CMD as this file is only compiled when CONFIG_CMD_REGINFO is defined Finally, this is a PowerPC-only command, disable it on a number of non-PowerPC platforms.
