FIRM

All files under RomFS were updated.

Package1ldr

package1ldr was updated. The TSEC secureboot firmware was not updated.

NX_BOOTLOADER

NX bootloader was updated.

Secure Monitor

The Secure Monitor was updated.

• DMA controller configuration now disables AHB-DMA from arbitration.
• The SMC handler now checks a "is SMC allowed" bitmask against configuration set by NX bootloader(This just comes from bits 1-4 of the "attribute" field of the bootloader in BCT).
  • Nintendo can now blacklist certain SMCs from certain boot conditions, but since the bitmask is zero for retail firmware (everything is allowed) this isn't particularly meaningful.
• smcGetConfig's "get_memory_configuration_by_bootconfig" implementation changed. It now calls a new function "get_dram_configuration", which returns a configuration value depending on the DRAM ID.
• Code configuring what peripherals to set secure-world only no longer assumes that the code is a retail unit.
  • This removes what were presumed to be compile-time ifdefs for retail vs dev added in 7.0.0.
• Code responsible for configuring HiZ charger mode has changed a little.
  • smcCpuSuspend no longer checks hardware type when deciding whether to go down HiZ mode codepaths.
  • wakeup code on warmboot now checks whether HiZ mode is enabled, instead of unconditionally disabling it.
• TSEC no longer has access to the kernel carveout, and TSECB now has access to the kernel carveout.
  • The Read/Write access levels were changed from 1 to 9, to facilitate this.

Kernel

Kernel initialization has changed significantly.

• There is now a new loader program ("kernelldr") that runs before the kernel, and sets up KASLR/memory/etc. (kernelldr has its own .dynamic section).
• The INI1 containing the Initial Programs is no longer its own section inside of Package2. It is instead now embedded inside the kernel section, with kernelldr preparing it for the kernel.
• svcQueryIoMapping no longer accepts unaligned addresses as input when (input physaddr >= 0x1000). In addition, when input physaddr is < 0x1000, the kernel takes a new codepath to convert this to a different physical address.

<check back later for more detailed diffs>

Warmboot

• The firmware revision magic was not changed.

FIRM Sysmodules

All FIRM sysmodules were updated. Specific diffs for a few sysmodules are below <check back later, to be updated>:

PM

• pm:shell now has a new command (9), which does abort() in normal FIRM. However, when in safe mode, it returns a handle to an event that is signaled on IShellService->NotifyBootFinished(), before the embedded safemode boot2 runs.

System Titles

• 1 new title was added: FunctionBlackList.
• All titles were updated, except for the following: dictionaries, UrlBlackList, PlatformConfigHoag, miiEdit, and flog.

FunctionBlackList

This contains /blacklist.dat which contains 8-bytes of zeros.
