The tools allow you to select chips or boards. If you choose a board the tools have awareness of the other hardware on the board.
I try to arrange it so that target hardware is compatible with the dev board (as far as possible) to ease the transition from dev to "real" h/w. I also try to only use chips that have a readily available dev board, but I realise that this is not always possible. The on-board debug support is very handy.
These days it's rare for me to have to look at register maps, I just use the apis provided.

Your latest comment is still pending and I'm impatient  so I'm responding here (I can see it via email)
Thank you for the advice. It's very helpful for me because I am looking as much as anything, for a usable workflow for developing with NXP ARM offerings, and it sounds like you have one that's not that complicated. Cheers. I owe you a beer.
And as far as avoiding the registers and using the APIs that's exactly what I was hoping for, vs using GCC and a raw toolchain+register maps. Thank you again.

Check out TI, they've got their own IDE (Eclipse based) that makes it relatively easy to get started. They have their own RTOS but it was easy to use FreeRTOS in a project I worked on.

If you want to aim lower than Linux, you might look at NXP's product line, e.g. the LPC1788. I've used this for several years now. You can get a completely free development stack. NXP's MCUXpresso as the Eclipse-based development environment, FreeRTOS as the kernel, emWin as the graphic library (free binary version from NXP), LWIP as the TCP/IP stack (FreeRTOS+TCP wasn't an option back then). Getting the first project off the ground takes a lot of effort, but after that it's pretty easy to clone off new projects. There are some development boards that can help you get your feet wet: Embedded Artists' board or e.g. smaller boards like this one or this one, along with one of their displays.

YAUT!. I was nearly going to put "made harder" so you had three 10 letter anagrams to consider.

Why is it that, when there's a choice of 2 or more single letters to complete a word, I always choose the wrong ones first?

Close one - choice of two for the last one, glad I went the way I did!

3 wrong choices for the first letter - same as me!
Get me coffee and no one gets hurt!

I just checked and there are 7 possibilities for the first letter, given the last 4.
So even if you got those 4 on line 1, you could still fail to get the word! 
[By the way, I don't consider this a spoiler, since anyone who reads this far into the replies must already have solved it or should be expecting to see 'hints'. Just seeing the diagrams gives almost as much info!]

Yep. Same problem! There were more possible words than guesses remaining after my 2nd word. So I decided to carry on "letter finding", rather than moving to "word guessing" mode - and managed to rule out another three possible letters with my 3rd try.

I was undecided between my second and third starter, I'd have gotten in 3 if I swapped them. Very fast and easy run this time for me.
