From: Marek Vasut Date: Sun, 24 Apr 2022 21:44:03 +0000 (+0200) Subject: ARM: imx: imx8m: Introduce and use UART_BASE_ADDR(n) X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=52b6b480db314d623eba536f390c0dc879900262;p=u-boot.git ARM: imx: imx8m: Introduce and use UART_BASE_ADDR(n) Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base address. Convert all board configurations to this new macro. This is the first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a clean up, no functional change. The new macro contains compile-time test to verify N is in suitable range. The test works such that it multiplies constant N by constant double-negation of size of a non-empty structure, i.e. it multiplies constant N by constant 1 in each successful compilation case. The non-empty structure may contain C11 _Static_assert(), make use of this and place the kernel variant of static assert in there, so that it performs the compile-time check for N in the correct range. Note that it is not possible to directly use static_assert in compound statements, hence this convoluted construct.
