* kernel: Enable UBI, FSI hub support and device tree updatesJoel Stanley2017-02-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces hub master support for the FSI driver, enabling it to initialise and talk to the FSI address space on the second socket of P9 machines. UBI and UBIFS support is enabled in the kernel in preparation for using them in OpenBMC. The P9 device trees have been brought in sync with each other, with all now describing the mailbox and lpc drivers necessary for using mboxd for host boot firmware communication.

* meta-aspeed: Add kernel panic timeoutXo Wang2017-02-131-0/+1
| | | | | | | | | | | | | Set a one-second timeout observed by the kernel after panicking. The system will reset after the timeout is up. The default timeout is 0, which means to wait indefinitely after panic.

* kernel: Add FSP FSI I2C driver and Zaius UART fixJoel Stanley2017-02-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bumps the kernel to include a port of the FSI I2C driver from the FSP. It drives the I2C master in the CFAM logic of the host processor over FSI. This driver is being rewritten to be a proper i2c bus driver, and as such will be removed once that driver is functionally equivalent. There is also a fix for the Zaius UART. A device tree for the Qanta Q71L, a non-openpower BMC, was added.

| | | | | | | | | High res timers are useful in general, particularly for userspace apps that call usleep(). Change-Id: I15be1b20141423650ed7f049a4b9ea53160260e3 Signed-off-by: Robert Lippert <rlippert@google.com> Signed-off-by: Patrick Williams <patrick@stwcx.xyz>
* Remove setting of explicit ramdisk load addressRick Altherr2017-01-041-3/+0
| | | | | | | | | | | | | | | | U-Boot in Aspeed's SDK had a hack to manually relocate the ramdisk into RAM because of a bug that caused the normal ramdisk relocation not to happen if ATAGS was being used. Now that the ATAGS ramdisk relocation bug is fixed, the load address and entrypoint of a ramdisk image are ignored. The ramdisk is relocated to an address chosen by U-Boot and the address is passed to the kernel. Remove the override of oe_mkimage() in obmc-phosphor-image_types_uboot as the default implementation is sufficient. This also removes the only reference to a fixed ramdisk location in RAM.

* kernel: FSI, Zaius LPC mapping and device tree fixesJoel Stanley2016-12-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | - FSI changes * Merge v1 of the FSI patchset as sent to lkml * Merge Jeremy's raw driver for slave address-space access * Define pins in Palmetto DTS * Build the FSI SCOM driver for both ast2400 and ast2500 systems. The driver has not been enabled in the device tree so it will not affect any sytems at this stage. We will enable systems as the userspace changes are made to support the kernel driver. - Zaius * Enable LPC to AHB mapping for flash access - Update the ast2400 systems with the correct amount of RAM * They systems have 512MB, minus the 16MB framebuffer, but our device tree restricted them to 256MB. * We now set them to 512MB with a 16MB no-map reservation at the top for RAM for the PCI framebuffer Change-Id: I7377e0f3bd075b78d923ff7295b133a75158e5d9 Signed-off-by: Joel Stanley <joel@jms.id.au>
* Move to the upstream IPMI BT kernel driverJoel Stanley2016-11-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel driver for the iBT interface has landed upstream. In the review process, the location of the device node was changed, as was the naming of the ioctls and the kconfig symbol. This change moves to the new version of btbridge, which brings in autotools support from Matt Barth and a port to the new kernel driver from Cédric Le Goater. The .bb file is modified to support the autotools dependencies. Convert build process to autotools replace bt_host by bt_bmc add a --device option Corrected resulting errors from -Wall & -Werror. We update the ast2400 and ast2500 defconfigs with the new config symbol, and bump the kernel to the latest version. The kernel changes clean up the old driver, and add the new one, including device tree changes.

* Fixed build problem by modifying CONSOLES variableJosh King2016-10-201-0/+3
| | | | | | | | | | | | | | Modified SERIAL_CONSOLES variable in the hardware systems so that we can get rid of the hacks file. The hacks file was used to manually stop the issue but now that is taken out and the issue is handled in the include files so the process doesn't start in the first place. This fixes issue number 586. Resolves openbmc/openbmc#586 Change-Id: I1eb54dae6cbec661f4b8865875e0fe5bd734c70c Signed-off-by: Josh King <jdking@us.ibm.com>

* Move to u-boot v2016.07-aspeed-openbmc branchJoel Stanley2016-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This moves all machines to a new u-boot branch. The u-boot branch is based on this month's upstream v2016.07 release, and contains cleanups that get us closer to submitting upstream. Importantly for the machine configurations, we now have four new defconfigs that replace the previous targets: - ast_g4_ncsi_defconfig: ast2400 with NCSI networking - ast_g4_phy_defconfig: ast2400 with directly attached PHY networking - ast_g5_ncsi_defconfig: ast2500 with NCSI networking - ast_g5_phy_defconfig: ast2500 with directly attached PHY networking We now support Firestone again with the ast_g4_phy_defconfig. This commit updates all machines to the new branch and defconfig. It also removes unused patches that were being made to u-boot, in the case of barreleye (a patch to aspeednic.c) and palmetto (a modification to the u-boot environment).
