hw/intc/armv7m_nvic: Fix byte-to-interrupt number conversions
In many of the NVIC registers relating to interrupts, we have to convert from a byte offset within a register set into the number of the first interrupt which is affected. We were getting this wrong for: * reads of NVIC_ISPR<n>, NVIC_ISER<n>, NVIC_ICPR<n>, NVIC_ICER<n>, NVIC_IABR<n> -- in all these cases we were missing the "* 8" needed to convert from the byte offset to the interrupt number (since all these registers use one bit per interrupt) * writes of NVIC_IPR<n> had the opposite problem of a spurious "* 8" (since these registers use one byte per interrupt) Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Reviewed-by: NPhilippe Mathieu-Daudé <f4bug@amsat.org> Message-id: 20180209165810.6668-9-peter.maydell@linaro.org
