System Titles

0100000000000824(Mariko Config), 0100000000000825, 0100000000000826 were added.
- 0100000000000824 provides configuration for the new "T214" SoC.
- 0100000000000825 contains an empty "/blacklist.dat" file.
- 0100000000000826 contains a 0x40-byte "/version" file, this is all-zero except for '0' at offset 0x20.

The built codebins now have padding in .text after every function for 0x10-byte alignment.

FIRM

Everything under RomFS was updated.

A new folder "a" was added, in addition to the existing "nx" folder, containing a separate "bct" and "package1". Both of these seem encrypted/meant for the new "Mariko" hardware that support was added for.

The following firm-sysmodules was added to both safemode-firm, which were originally in separate sysmodule-titles: Bus, PCV, and psc.

All firm-sysmodules were updated (might be due to updated (?) rtld).

Secure Monitor

The Memory layout was changed significantly:

.text, .rodata, and .data are now separate sections, instead of being mapped RWX.
Physical layout in TZRAM changed significantly, with pk2ldr being in low TZRAM instead of high TZRAM.

In addition, there were changes to the SMC interface:

smcLoadSecureExpModKey no longer exists.
smcLoadRsaOaepKey has been replaced with a new SMC (0xC300D60C) that loads two keys into TrustZone.
smcGetConfig was extended with two new config items:
-GetConfig(16) now does the following, which seems to check whether the Switch is running on a Tegra 210:

   return (FUSE_RESERVED_ODM4 & 0x800) &&  FUSE_RESERVED_ODM0 == 0x8E61ECAE &&  FUSE_RESERVED_ODM1  == 0xF2BA3BB2 ?  (FUSE_RESERVED_ODM2 & 0x1F) : 0

Getconfig(17) now checks whether package2 is plaintext or encrypted.

Kernel

Kernel Address Space Layout Randomization was added.
- Instead of using a hardcoded address for per-CPU region, they now use x18 to point to the per-CPU region.
6 new syscalls

Internet Browser

OSS/WebKit was updated.

In the NPDM, besides the RSA region the only changes were the kernel-release-version descriptor + {new ACID flag is set}.

NPDM

New flags bit2/bit3 were added to the flags at ACID+0xC.

Keys

Keyblob 5 is now used, instead of 4. New NCA keydata is now used as well.
