arm64: Correct passing of Linux kernel args

2014-08-30T11:46:40Z

The Documentation/arm64/booting.txt document says that pass in x1/x2/x3 as 0 as they are reserved for future use. Signed-off-by: Tom Rini

ARM: convert arch_fixup_memory_node to a generic FDT fixup function

2014-07-28T15:19:49Z

Some architecture needs extra device tree setup. Instead of adding yet another hook, convert arch_fixup_memory_node to be a generic FDT fixup function. [maz: collapsed 3 patches into one, rewrote commit message] Signed-off-by: Ma Haijun Signed-off-by: Marc Zyngier Acked-by: Ian Campbell

ARM: HYP/non-sec: allow relocation to secure RAM

2014-07-28T15:19:09Z

The current non-sec switching code suffers from one major issue: it cannot run in secure RAM, as a large part of u-boot still needs to be run while we're switched to non-secure. This patch reworks the whole HYP/non-secure strategy by: - making sure the secure code is the *last* thing u-boot executes before entering the payload - performing an exception return from secure mode directly into the payload - allowing the code to be dynamically relocated to secure RAM before switching to non-secure. This involves quite a bit of horrible code, specially as u-boot relocation is quite primitive. Signed-off-by: Marc Zyngier Acked-by: Ian Campbell

ARM: HYP/non-sec: move switch to non-sec to the last boot phase

2014-07-28T15:05:59Z

Having the switch to non-secure in the "prep" phase is causing all kind of troubles, as that stage can be called multiple times. Instead, move the switch to non-secure to the last possible phase, when there is no turning back anymore. Signed-off-by: Marc Zyngier Acked-by: Ian Campbell

armv8: Flush dcache before switching to EL2

2014-04-07T20:19:00Z

For ARMv8, U-boot has been running at EL3 with cache and MMU enabled. Without proper setup for EL2, cache and MMU are both disabled (out of reset). Before switching, we need to flush the dcache to make sure the data is in the main memory. Signed-off-by: York Sun Acked-by: David.Feng

common/cmd_bootm: extend do_bootm_vxworks to support the new VxWorks boot interface.

2013-12-16T13:59:05Z

The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware description mechanism. For PowerPC, the boot interface conforms to the ePAPR standard, which is: void (*kernel_entry)(ulong fdt_addr, ulong r4 /* 0 */, ulong r5 /* 0 */, ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */, ulong r8 /* 0 */, ulong r9 /* 0 */) For ARM, the boot interface is: void (*kernel_entry)(void *fdt_addr) Signed-off-by: Miao Yan [trini: Fix build error when !CONFIG_OF_FDT is set, typo on PowerPC, missing extern ft_fixup_num_cores] Signed-off-by: Tom Rini

ARM: extend non-secure switch to also go into HYP mode

2013-10-03T19:28:55Z

For the KVM and XEN hypervisors to be usable, we need to enter the kernel in HYP mode. Now that we already are in non-secure state, HYP mode switching is within short reach. While doing the non-secure switch, we have to enable the HVC instruction and setup the HYP mode HVBAR (while still secure). The actual switch is done by dropping back from a HYP mode handler without actually leaving HYP mode, so we introduce a new handler routine in our new secure exception vector table. In the assembly switching routine we save and restore the banked LR and SP registers around the hypercall to do the actual HYP mode switch. The C routine first checks whether we are in HYP mode already and also whether the virtualization extensions are available. It also checks whether the HYP mode switch was finally successful. The bootm command part only calls the new function after the non-secure switch. Signed-off-by: Andre Przywara
