From 9a5483e9df9557c1387e9a0c15c881e6f0278448 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 3 Apr 2018 12:52:48 +0200 Subject: ARM: rmobile: Add TPL support on R8A7791 M2 Porter Add and enable TPL on M2 Porter. The TPL must fit into 16 kiB due to the Gen2 BootROM restriction. The TPL is running from MERAM and is capable of performing the initial initialization of PFC, Clock, GPIO, LBSC, DBSC and QSPI NOR. DBSC is responsible for bringing up the DDR DRAM access. The TPL is capable of loading the next stage, U-Boot, from either SPI NOR or UART as a fallback. If either does provide a valid U-Boot uImage, the system stops, which allows the operator to load U-Boot ie. via JTAG and start it manually.
