-- 2.20.1 Since commit ba3e7926691ed3 it has been unnecessary for target code to call gen_io_end() after an IO instruction in icount mode; it is sufficient to call gen_io_start() before it and to force the end of the TB. Many now-unnecessary calls to gen_io_end() were removed in commit 9e9b10c6491153b, but some were missed or accidentally added later. Remove unneeded calls from the arm target: * the call in the handling of exception-return-via-LDM is unnecessary, and the code is already forcing end-of-TB * the call in the VFP access check code is more complicated: we weren't ending the TB, so we need to add the code to force that by setting DISAS_UPDATE * the doc comment for ARM_CP_IO doesn't need to mention gen_io_end() any more Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru> Message-id: 20200619170324.12093-1-peter.maydell@linaro.org --- target/arm/cpu.h | 2 +- target/arm/translate-vfp.inc.c | 7 +++---- target/arm/translate.c | 3 --- 3 files changed, 4 insertions(+), 8 deletions(-) diff --git a/target/arm/cpu.h b/target/arm/cpu.h index XXXXXXX..XXXXXXX 100644 --- a/target/arm/cpu.h +++ b/target/arm/cpu.h @@ -XXX,XX +XXX,XX @@ static inline uint64_t cpreg_to_kvm_id(uint32_t cpregid) * migration or KVM state synchronization.

Most important registers are those related to DRAM initialization and calibration, where SPL initiates process and waits until certain bit is set/cleared. This patch adds these registers, initializes reset values from user's guide and updates state of registers as SPL expects it.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.
